Looks good!

Are you sure about keeping the big fonts in "Edit | Quote..." The font used in the default theme is good already.

A small detail I really like about the Minimalistic that should be adopted b the default theme is the bigger clickable area around the number of posts in the "New" & "Today" listings. Super finger-friendly. In the default theme the number is also big but the clickable area covers the number and nothing else. The extra surface in Minimalistic makes it much more usable e.g. when sticking the finger to pop up the 'Open in new page' dialog.
