 The desktop entry (`MimeType` + `Exec %f`) makes PLWL show up in Dolphin/Nautilus under **Open With** for Windows executables (`.exe`, `.msi`, `.bat`, `.cmd`, `.lnk`). Opening a file that way shows a small popup in the launcher where you pick the **Wine/Proton version** and the **prefix** for this run — both default to the launcher's defaults, nothing is imported into the library. A second launcher instance hands the path to the running one and exits (same single-instance mechanism the shortcuts use).
 
-The app shortcuts created in an app's configuration work as **Open With** targets too: pick one in the file manager (right-click a photo → Open With → your Photoshop shortcut) and that app starts with the file, receiving it as the Windows path it would get on Windows — `C:\...` when the file sits inside its prefix, `Z:\...` for the rest of the machine. Giving a file to an app that is already running hands it to that instance instead of starting a second tracked run.

 - **Sync code** - 8 characters, letters and digits, case-insensitive. A device only accepts a connection when the caller proves it knows *its own* code; each verification costs two seconds and a device may only have one in flight, so guessing over the LAN is pointless. Both the ID and the code can be re-rolled. A correct code is still not enough: the receiving device shows an **Accept / Decline popup** before anything moves, and without a click within a minute the sender is turned down. Declining (or ignoring) the popup never touches this machine and does not unpair the two devices.

-**Both machines show what is happening.** The sender gets a progress popup and the receiving device gets the same popup titled *Receiving from X…*, driven by the transfer as it arrives. Both show the current phase and unit, the files being moved, a sent/total counter per category (`Apps: 2/5 · Prefixes: 1/2`) and the transferred vs. planned size. The bar follows **bytes, not file counts**, and it belongs to the phase being worked on: hashing fills its own bar and the transfer starts again from empty, so nothing ever looks finished while it has just begun (the byte line next to it keeps the overall transferred vs. planned total). Both popups warn that the launcher must stay open, and a running sync is not cancellable from the outside: clicking the backdrop or pressing Escape does nothing. If the other device goes quiet for a few seconds (it hashes before it sends) the popup says *Waiting for the other device…* rather than closing, and the sending side keeps signalling while it works, so even a long hashing phase never looks like a dead peer. The popup closes itself when the transfer ends, or after fifteen minutes of complete silence when the other side has really vanished — and comes back if the sync turns out to be alive after all.

 The **sending device is the source of truth**: files that differ are overwritten, missing ones are written, and anything living only on the receiving side inside the synced trees (`files/apps/`, `files/wines/`, `files/wineprefixes/`, `files/data/icons/`) is deleted. Files are compared with a fast, collision-resistant hash (BLAKE2b-512, SHA-512/SHA-256 fallback); **Force sync all files** skips the comparison and overwrites everything instead. Hashes are remembered per file (size + modification time), so a repeat sync of a library that did not change reads nothing at all.
 
 **Wine builds and prefixes survive the trip.** Permissions travel with a sync, so the `proton`, `wine` and `wineserver` binaries are still executable on the other machine (a build whose executable bit was lost is additionally repaired at startup, without re-importing it), and symlinks are sent as RELATIVE paths whenever the file they point at belongs to the launcher: a Proton prefix is full of links into its build, and the receiving side gets links that resolve to its own copy instead of the sender's `/home/...` folders. Links that leave the launcher on purpose (`dosdevices` drive mappings, a mounted drive, the user's home folder) stay absolute, and links into a folder that does not exist yet on the other machine are still written relative, so they start working the moment that folder appears. Wine and Proton rewrite a prefix's links with local absolute targets while they update it; PLWL relativizes them again on the wire, on import and before every run.
 
-A sync also carries **how the apps are set up**: the Wine/Proton build and prefix each app runs in, its arguments, environment variables and DLL overrides, plus playtime and last played. The **Sync settings** category carries the registry-level part of that even when no files move: the launcher's **default Wine build and default prefix**, the custom **names** you gave Wine/Proton builds (and their disabled flags), the **prefix registry**, every **app's configuration**, and the **order of the library**. It only patches what already exists on the other machine - an unknown Wine id or prefix is ignored instead of leaving a dangling default or a broken app behind, apps and prefixes the sender does not know stay where they are, and a settings-only sync deletes nothing (that is what the file categories are for). Playtime only ever grows - the higher counter wins - so pushing from a freshly installed machine cannot wipe a library's play history. Everything else stays local: language and window settings, logs, translations, and external (leave) apps - prefixes are always kept usable, so app entries pointing inside a prefix keep their prefix-relative paths and the receiving side never loses its own `Main` prefix.

 ## Wine & Proton support
 
 - **System Wine** — uses the `wine` binary from PATH.
 - **Imported builds** — drop any wine or Proton build into `files/wines/`. The folder may contain the build directly, or one level of nesting (zip-extracted layouts are detected automatically). After the copy, PLWL rewires the build's absolute symlinks to relative ones and restores the executable bit on the binaries it needs to run (`proton`, `wine`, `wineserver`, `winetricks`), so a build that arrived from a zip or another machine works without further fiddling. A build can also be given a **displayed name** of its own (Wine versions): it is used everywhere the build is offered — library config, settings and the *Open with PLWL* popup — while the folder in `files/wines/` keeps its name and the symlinks inside prefixes stay valid.
-- **Proton without Steam** — fully supported. Proton is invoked like Steam does it: `STEAM_COMPAT_DATA_PATH` is a per-build compat folder linked to the launcher's own prefix, and `STEAM_COMPAT_CLIENT_INSTALL_PATH` points at an installed Steam client when there is one (Proton reads its legacy DLLs and `steamclient.so` from there, read-only) and at the empty `files/data/fake-steam` otherwise. GE builds work out of the box: PLWL launches through Proton's built-in UMU path (`UMU_ID`), which needs no Steam client at all. An app that breaks under umu.exe has a per-app **Disable UMU** switch in its config — PLWL then runs the build's own wine directly (Proton's `runinprefix` verb): no umu.exe/steam.exe launcher and no Proton prefix setup take part, so the run stays as close to plain wine as possible. (Proton's session init still reads `STEAM_COMPAT_CLIENT_INSTALL_PATH` on every verb; a disableUmu run gets the empty `fake-steam` folder and nothing is copied out of it.)
+- **Proton without Steam** — fully supported. Proton is invoked like Steam does it: `STEAM_COMPAT_CLIENT_INSTALL_PATH` points to a fake steam client folder, `STEAM_COMPAT_DATA_PATH` is a per-build compat folder, and the prefix lives at `<compat>/pfx` which PLWL links to its own prefix folder. No Steam installation required (GE builds work out of the box; for a few Valve builds that refuse to run without a client, PLWL fakes a minimal steam folder in `files/data/fake-steam`).
-- **One C: drive per prefix** — Proton normally keeps its prefix one level deeper (`<compat>/pfx/drive_c`) than wine (`<prefix>/drive_c`), which left a prefix used with both kinds with two separate C: drives (two registries, two sets of saves). Whenever a prefix has no `pfx` yet (a fresh prefix, or a plain-wine prefix first used through Proton), PLWL makes `pfx` a relative symlink back to the prefix itself, so Proton and wine share one `drive_c`, one registry and one `dosdevices`. Existing layouts are left exactly as they are — prefixes from older versions keep their real `pfx/` folder, and a prefix with both `drive_c` trees keeps both, because two live Windows installs cannot be merged safely (both stay visible to the prefix import picker).
