A few of points.1. Include a tick box in the options to zap the splash screen. I know you can do it from the command line but that's a bit old fashioned (or is it me?).
2. Have an option to remember the last used root for the various scans (main database scan, duplicate search, moved songs, etc.
3. Incidentally, the moved song search should need the user to select a song first...
4. The database context actually shows the media that is the host. To my mind this is wrong, it should just show the folder(s) that are at the top level of the various trees.
5. The Computer context should offer the option to add to and delete from the database material that falls into the scope as determined by the filetypes selected in the options. At the moment all you can do for files that aren't in the database is actually delete them from the disc.
6.The duplicate search results would benefit from the ability to sort & filter, especially if the list is long.
All 4 now.
