Reduce crashes and ui jitter and hanging by improving ui-db async code
Speed up tagging workflow and autocomplete results
Add ways to display files in ways other than thumbnails (like 'details' view in file explorers)

Add Ugoira support (including optional mp4/webm conversion)
Add CBZ/CBR support (including framework for multi-page format)

Write a repository-client refresh/resync routine to clear out junk data and save space
Prototype a client api for external scripts/programs to access

Add an optional system to record why files are being deleted
Improve file lookup scripts and add mass auto-lookup
Cleanup code and improve practises
