In no particular order,

Decrease the default slice sizes so that they actually fit on
the media. E.g., an 80-minute CD-R cannot handle a 703 MB slice.

Implement an archive database manager.

Allow user to stop libdar operation prematurely.

Make KDar run in daemon mode, and allow user to schedule a backup
profile for periodic execution. Daemon mode may be as simple as 
minimizing KDar into an applet in the taskbar system tray.

Get progress bar to work with all libdar operations (not just creation).

Improve GUI layout. Suggestions? Comments?
Suggestions for new logo/icons for KDar are always welcome.

Implement scrambling option, input, output pipes, etc.

Fine-tune context menu. Allow a single directory, or entire subtree to 
be restored.

Make icons in archive browser more specific (jpg, xcf, etc.).

Popup window to show archive properties (size, number of files,
compression ratio, creation date, computer and root directory that
it was created from, whether it has been validated, date of last diff,
creation options, etc.)

Allow user to preview the restored directory tree, before they do
the actual restoration. Should update in response to changes in
the file and directory filters.

Given a directory to backup, show a tree of that directory, and highlight
or otherwise mark the directories and files that will be archived.
This should update in realtime as user changes directory, file and 
compression filters.

I welcome your feedback on KDar. Any suggestions?
