have a few more feature ideas now after using it a lot more. will keep updating this reply and top post when I have new ideas. ideas will crossed out when added.
Extra features:
1. music data export, add .ust, .kar (MIDI-Karaoke) and Lyric Meta-Event format support to match phonemes
2. closest rhyme match dictionary, for selected phonemes on the piano roll (changes your next phonemes into the result)
3. save export project path for current session and reimport
4. version numbering option for "export project" menu
5. importing lyrics from midis (see Extra Features. 1) to match with notes
