I agree (in part) with Tickly, don't turn it into Fruity.
Keep the pattern interface the way it is, or else it won't be a tracker anymore, besides I can't stand Fruityloops's (and other newer apps) way of putting everything on buttons. I know it's done to mimic real hardware sequencers and drum machines, but let's not forget that this is software, there *are* better ways than buttons, besides, point and click interfaces can only go so far as far as productivity is concerned, once you're in a routine point and click is simply too slow (and a hassle). Even though I'm currently a Reason user, I *never* use the buttons on the drum machine because it's limited what you can do with it compared to a full sequencer and (as I said before) a hassle to use.
The usual tracker interface would be ideal for me, though with the ability to colour some rows in a different colour so you don't get lost in the rows and columns.
I do agree, however, that a more easily managed 'song mode' as Simo calls it would be a good idea. That's where I usually get lost when using trackers once the song gets too big with too many parts (or patterns or whatever you call them).
