Truthfully, I like a little of them all. Customizable with a two-level functionality and scrollable/hidden as appropriate. That said... that's a massive pain in the butt for something that's setup once and then generally just left alone.
I personally know I have my very few functions that I do daily on mobile.. For me, I only really need The Date, the Right Indent (left indent can be done with enter so I don't use that dedicated button), and the complete item check.
But I know my usage may not be yours, and may not anyone else's. So I think that the customizable would be nice for everyone to have a few "most used" favorites, but I I think a 2-level menu doesn't try to conform to anyone's need and gives everyone all the functionality they may desire, even if it means a couple more taps. And finally scrollable because even a multi-level menu may still not quite fit in portrait mode
