Good one!

Lots of nice features, there is only one I could see now that is missing or not very smart: tiled galleries do not interact with normal pictures. If I have both pictures and galleries in a post, galleries would open very nicely, but pictures open by default in the whole window/tab; this forces me to use some kind of plugin for having javascript popups with those normal images; the side effect is that there is no common functionality between normal images and galleries.
