Just upgraded to 21. Having been away in osx/bash for awhile, I thought it was neat to see the RegEx tool. It could use some love though... It would be nice to have a syntax selector - the one great thing about this over *nix is the syntax selection, but it would be great to do investigation/testing on the fly. Support group matching feedback. () style groups are great, especially since there is support for groups in some of the functions. Maybe I'm missing it, but a way to launch it as a command would be nice (yeah, I know I can key bind it).
