0.4:
- hide user/hidden category from the advanced listing too, but show in removable apps (does removing them work?)
	- a "hidden" command line option to show it?
- better progress indicator during package download (try to show actual progress)
- make it possible to cancel while performing certain operations (downloading packages, updating catalogs)
- better repository UI
- show what repository a package is in ("apt-cache dump" shows this)
- prompt for autoremovable packages when running cleanup

- promote this version to -testing when ready?


later/any:
- store/load package selections
- configurable catalog update settings (time interval, always automatic)
- support loading .install files
- install .debs directly to interact with the Ovi store (need to research the ovi store stuff a bit)
- allow user to hide certain packages (forever, or until a new version becomes available)
	- add an additional category filter for them so they can be unhidden
- support localization/translations (both UI and in package data)

unknown/impossible:
- add filter to sort packages by date (where can I get the date information from?)
- lock package database (fcntl) - how to not cause conflicts when calling apt-get?
