Decent so far.. but.

Nice app so far, however the help screen scrolls at an excessively slow rate when using the two finger trackpad scroll. Not consistent with OS settings that apply to scrolling in other apps. (On Macbook Pro, OSX Lion 10.7.2)

Also, it would be nice to be able to have multiple windows open at a time, to be able to try different regex options without losing your work on the first one. Would rate 5 stars if these features were fixed/added.
