I'd love to see a MilkyTracker V2 (Redesign). I think that the current layout is a bit jumbled. It confuses you at first.
First off, it would be nice to have the "File", "Edit", et cetera where we can easily find functions like 'Export' (known as "record" currently).
I had to ask how to export because I didn't see any obvious button.
Next, I think that some overall layout could be improved. I completely missed the "Scale" option when I was trying to optimize it for my television, and the resolution just resizes the boarder...
Also, why of all things is Caps Lock the 'sample stop marker' hotkey? Can right-clicking in the notes area bring up a menu that lists the different music functions and hotkeys?
Also note that the background behind the credits is bad contrast with the font. I think the credits box could be improved to display the image, then cut to (at least mostly) black and have the credits roll vertically.
Basically what I am talking about would be a modern redesign.
I still don't know how to curve notes.
