Fixes
- A slow filesystem-event startup step no longer risks freezing the app a few minutes after launch
- No more freeze when a selected file sits on a slow or disconnected drive, caused by the script action bar checking each file's type on the main thread
- No more freeze during the periodic background reindex, caused by a cache refresh that could stall behind the running scan
- Settings sidebar no longer collapses out of view with no way to reopen it
Improvements
- If the app ever quits unexpectedly, it now restarts itself and saves a crash report each time, so the cause can be tracked down
- Restyled settings sidebar
