the 1.88 milestone:
* the most "intrusive" changes to ui should be done at this point: the detailed
  package view and package browsing interface, improvements to the filtering ui 
- make the filter area resize itself to fit the contained filters [done]
- clean up individual filters (their extended state that is) [done]
- implement a sidebar for listing available filtering options
- implement "buckets" for wanted and unwanted tags (these are basically a
  want/unwant anded tag filters)
- implement drag&drop from sidebar to buckets and to filter list
- implement shuffling of items in the filter list by d&d (needs fixes in
  extendablelist)
- implement detailed package view
- implement package browsing (needs thinking)

* basic pinning support in the libraries should be done (the ui will possibly
  have to wait till beta) 

* the ui should be fully i18n'd 
- libapt-front needs to be i18n'd
- strings in libept and apps need to be wrapped in i18n

* skeleton of the update notifier should be done 

* purge and reinstall options in the UI 
- need respective options in libapt-front
- add actions to context menu
- think about semantics...

* support for individual deb handling in the libraries (possibly without
  ui) 

* at least basic support for konsole hiding (eventually without "waiting
  for input" detection)
