Yes, you can display TXT, RTF, JPG, PDF.... lyrics, linked to songs/styles....
You can assign 2 buttons to PAGE - / PAGE +
You can save the Lyrics position and size in the screen
You can assign a button for the LYRICS HIDE / SHOW
You can plug a second screen in your laptop for the Lyrics

Sliders and buttons are better for most used functions, like Arranger variation , A B C D, fill in, start/stop...

To change styles, I prefer to use the touch screen

For now, vArranger doesn't gess the SMF chords

When you save song, it memorizes the on load variation/intro, and part volumes etc
