My only problem with Monokai is I find it impossible to see small selections in the minimap. If selections stood out more in the minimap (which would be quite a useful feature, actually) I'd be all over Monokai.
What if selections on the minimap were outlined like find results in the normal view, or something similar? Or what would also be cool is if there were arrows at the top and bottom that said something like "x more selections above/below" so you could quickly tell where all your selections were.
Summary: Monokai is nice in the normal view, but not in the minimap.
