I've been exploring the beta. Overall pretty nice, but here's the problem areas that I've run into significant items that need to be addressed before full release:
Library manager -
1) The Backup and Restore buttons are not functioning at all.
2) OK, this one is complicated to explain. I don't use the standard path for the library location. So when I upgraded (uninstall ver. 8, install ver. 9) it reverted back to the old library files that still existed in the default directories. So I added a new library at the location that my old library files existed. No problem. Except that now I had BOTH libraries showing in MJ, rather than only the current one I loaded (no, I didn't select "Merge"). I tried deleting the old one, but it didn't remove the double entries. I finally deleted both, restored my old library files manually to the directory, edited the registry to point the library to the correct directory, and restarted MJ. It had to re-convert everything (obviously) but now it's fine. I'm not going to try to create another library, until this is fixed, though.
3) Update Library doesn't work properly. It reverts the library path to the default MJ setting rather than using the correct path for that library. So if you're not using the default directory, suddenly your entire library is blank and it says that it removed every song!
Lists -
1) User cannot control what directory Export All Playlists goes into - should be user definable option
2) User cannot control which playlists get exported when doing "Export All" - should be user definable on a playlist by playlist basis
3) MJ exports blank playlists when doing "Export All" - should be user definable option (or simply should NOT export blank playlists)
4) User cannot export playlist "groups" when doing "export all" - should be user definable option (preferably on a group by group basis, but at least a general option of whether to export groups or not as a global setting)
5) Possible bug: performed Export All Playlists while playing a song and after export (and dialog box saying export was successful), program crashed.
6) In Export Playlist dialog box, the button "..." to open file explorer to select the filename location does not function.
7) Smartlist wizard is not helpful for creating searches looking for empty properties. Should have simple selection box to "search for null".
8) User cannot permanently delete Auto Smartlists. This is especially annoying since we cannot control which playlists are exported when doing an "export all" (as mentioned in #2 above).
9) Other jukebox programs have a setting that says "export all playlists on exit". That would be a very nice option to have!!!
Tools -
1) When doing a "Move/Copy Disk File" command, it didn't seem to update all the filenames properly. File remained in library pointing to old invalid paths. I haven't tested this fully. It may have occured when doing a Rename File based on properties. But definitely one of those commands created invalid path entries in the library because it didn't update the path after it moved the files.
2) Locate File (on disk) causes the program to hang. (though I'm not really sure what this command is supposed to do.)
