 - Added an anime browser window that searches Aniyomi extension sources, shows cover art and episode lists, and plays an episode in mpv so the overlay and mining tools attach as usual.
+- Browser failures show a dismissible explanation with next steps and expandable technical details, including the bridge's error response instead of only its HTTP status.
 - Added `subminer anime` and the `--anime` flag to open the browser, plus a "Browse Anime" tray entry.
 - Anime extensions are read from `<userData>/anime-extensions`; drop Aniyomi `.apk` files there to add sources.
 - Added a source settings tab so extensions that need configuration (server address, credentials, quality) can be set up from the browser; values persist per extension and source, and updated extension schemas replace stale saved field definitions without losing values. Older unscoped preferences are discarded once because their package ownership cannot be proven safely.

 - Episodes can be queued instead of replacing what is playing. Every episode row has **Play** and **Queue** buttons (clicking the row still plays now), the right-click menu offers the same two, and a queued episode shows its place in line ("next up", "#2 in queue") with a queue count and **Clear queue** in the episode header. The queue spans anime, resolves and appends each episode to mpv's real playlist as soon as it is queued while subtitle tracks cache in the background, so next/previous navigation works immediately and the next episode starts without a resolution pause when the current one ends. Queueing with nothing playing just plays.
 - Added an in-player Anime Browser modal on `Ctrl+Alt+A`. The shortcut toggles it without losing its page or scroll position. It stays within the player bounds and shares the active episode, playback queue, source configuration, and watch history with the standalone browser, while each surface keeps independent search and navigation state. The modal validates its embedded page before changing overlay state, so a load setup failure leaves it closed rather than revealing a broken modal. The SubMiner logo identifies the Anime Browser in both the modal and standalone window.
 - The bridge is reused from a package-manager install when one exists: on Arch the AUR `mangatan-extension-server` package (shared with Mangatan) is picked up from `/usr/share/mangatan/extension_server`, so nothing is downloaded and pacman keeps it current. `anime.bridgeDir` points SubMiner at a bundle anywhere else. `subminer-bin` lists the package as an optional dependency.
-- SubMiner records which bridge release it installed and, once the bridge is running, checks GitHub for a newer one; when there is, the banner offers an **Update to vX** button. The new release is downloaded beside the running bridge, then the bridge restarts on it. The updater waits for a bridge still starting to stop and keeps the previous bundle until the replacement is active. The Extensions tab shows the bridge version, where it lives, and who updates it without describing an unchecked install as current.
+- Once the bridge is running, SubMiner checks GitHub for a newer release, including for AUR and custom installations. AUR update notices direct users to their AUR helper; custom installs get manual-update guidance. Only SubMiner-managed copies offer an **Update to vX** button.
