-later/any/uncertain:
-- fetch dates from other repositories than maemo.org?
-- fetch dates for other than user categories?
-- update install/remove changes directly to internal package db & don't require re-reading package lists afterwards
-- add an option to start fetching changelogs automatically for all upgradeable packages?
-- how to handle package names that end in '-'? (theoretically they are valid but nonexistent?)
-- ability to easily add extras-devel and extras-testing to repos if they don't exist
-- load package lists in the background when the main menu is visible?
-- possibility to force reinstall of an already installed package
-- warn about unauthenticated packages / option to disable installing unauthenticated packages
