N900 really needed an app manager replacement. I have some wishes for fapman:
1. Optimize it for large number of packages. Filtering works very slowly when package list has more than 10000 entries.
2. Package list should be cached. Users should not be forced to wait as the list is read from apt. Package lists should be shown immediately after user selects Install from menu. The update should take place in background while user is browsing cached list. When update is complete it should be merged with cached version and UI should update in a way user can barely notice.
3. I would like to have an option to see live log during apt operations.

Keep up the good work!
