The UI needs to be completely revised. Saving existing drum maps is too confusing. The buttons are placed in weird positions. How the rows behave when altering them is perplexing. I can't test to see if a setting works until I exit preferences (so time consuming)... Of course I know how to workaround all these oddities now, but it's simply dreadful.
I can understand why drum maps were hidden in preferences in the past (they didn't work very well), but now they are working I hope Cakewalk scraps the UI and gives up a decent UI interface for drum maps in the multidock soon. This, fixing track templates and takelanes are top on my list.
