Anyone who's ever had to navigate through the SourceForge bug tracker to track down a reference to "Tk bug #12345" will appreciate the "Jump directly to a project's bug or patch by number" form at <URL: http://tcl.sourceforge.net/ >. This is much easier to use.
I've wrapped this little goody up into a Mozilla sidebar, along with quick links to other useful stuff. You can find it here:

Hope others find this useful.
