Gerd Knops has released version 1.0 of TmCodeBrowser:
TmCodeBrowser is a TextMate plugin designed to help navigating source files. It will parse any language known to the underlying Exuberant Ctags program (enhanced by a small script to also support Objective-C). It will present classes, subroutines etc. in a TreeView. Clicking on any entry will jump to the corresponding location in the source code.
My hat goes off to Gerd for putting this together and releasing it to the public!
