- Particularly in the addons list
Download Addon statistics from central location.
- Allow sorting on those statistics.
Download a "rank" from user-specified locations.
- Allow sorting on that rank.
Implement a server-side cache of Addon metadata.
Implement an "offline mode" that does not attempt to use remote data for anything.
When installing a Preference Pack, offer to apply it once installed, and to undo after that.
Better support "headless" mode, with no GUI.
Add "Composite" display mode, showing compact list and details at the same time
