The best would be, when we could have a zoom in the tracker view:
But i generally dont like note off. It clutters the note columns too much. I often used phrases, where a C note + a note off was in, so i can focus more on the melody and i used the cut command or a seperate note off, when i want a “faster” note off. An invisible auto note off would be cool, where i can set the default note length to 8tel and use note offs or cut for 16tel or even 32tel.
