0.7.0 (all of these can go under "known limitations", that
       is, they are not release-critical IMO):
1) update namespace content (not implemented)
2) various minor memory leaks (see FIXME in search.c, 
   #if 0 code in namespace.c)

Later (0.7.1+):
0) better file-name selection, in particular for downloads from directories
1) create directory from known file IDs [ medium ]
2) disable inactive buttons (if no search/download 
   is selected to operate on) [ medium ]
3) more help-texts (glade) [ easy ]
4) highlight completed downloads [ easy ]
5) highlight active downloads in search list [ easy ]
6) pop-up dialogs / context menus (show extra information,
   in particular full metadata) [ medium ]
7) chat [ difficult ]
8) show content of current collection


gnunet-gtk wishlist (from pre-0.7.0 days):
- add option to list all indexed files and perhaps delete from them
  (ECRS now supports listing of indexed files!)
- for potentially long clists, add option to specify a string
  pattern that must be matched for the lines to be displayed
  (to further prune search results, for example)
- implement search bookmarking (e.g. user could add/edit/delete
  favourite namespace/key etc combinations)
- in Assemble Directory's Files Available/Selected
    Add sortability
    Add multiselection
    Print filenames as well
- add right button popup menu operations for
    Select by pattern
  in the search result list.
- a completely new interactive namespace/directory building
  module that would allow importing files/directories from
  disk and edit various parameters, file descriptions and
  the dir tree structure before the insertion.
- give user opportunity to change namespace rating after
  namespace download succeeded
