Sherry,

Thanks for your report on MidiNotate Player. I have confirmed the problems with:
(2) no tutorial-- it's simply not yet implemented
(3) missing button hover hints
(4) play button doesn't turn off at end of song

I'll need to re-think whether MidiNotate Player should save files. It is important that MidiNotate Player let the user add key signatures and clef changes to imported MIDI files. If that is important, then it should also be important that the user can save these simple changes. Therefore, MidiNotate Player probably needs a File Save (save as .NOT file) command, as well as the back-door method of saving the file you discovered (and which I was not aware of), which is that MidiNotate Player will ask you whether to save the edit file upon exiting.

I'll investigate the second part of your #5 item after I add File Save back into MidiNotate Player.

Thanks for your valuable feedback on MidiNotate Player.

Cheers
