Where can I find documentation or a user manual for kGTD?
Well, there is this FAQ for starters. The Kinkless homepage has a guide to using the Quicksilver action and an introduction video demonstrating kGTD’s installation and basic use. Currently (as of July 21, 2006) there is no other documentation available at Kinkless, but a user guide is said to be forthcoming(don’t hold your breath). The forums there also have some tips for use and troubleshooting.
