When backing up the flashcard database, I notice that the default name is now flashbackup-X.pqb, where X is some long number that changes each time. Is it possible to change this? Before, I used to just save it as flashbackup.pqb and mark it as a favorite in Dropbox so that it was easy to automatically keep changes synced between my phone and tablet. Now, it won't automatically sync unless I edit the filename back to flashbackup.pqb every time I save, or go into Dropbox and manually upload it. This is more Dropbox's fault than Pleco's, but if it's easy to at least add back the option to set the default filename for the backed up database, that would be very useful.
