Things I like include:
- Superb find/replace dialog box including:
--- Multi-file find/replace
--- Option key limits find/replace to selection
--- You can choose whether the window stays open or closes after a find
--- Whole word checkbox (faster than using a regular expression)
- Compact window toolbar with useful tools

Things I don't like include:
- No support for tabbed windows
- No support for scripts (though it has a nifty terminal-like worksheet)
- Cannot insert spaces instead of tabs when one hits the tab key. (I personally prefer real tabs but spaces is a required style for many).
- The Python mode needs work. Functions are not parsed (the function menu is empty) and comment/uncomment uses // instead of #

Overall it looks very promising but has some rough edges.
