Easily the one program that I was most excited to stumble upon. If you have a notebook that can use the multi-touch gestures, this is a must!

Multiclutch is a very simple program that is installed as a preference pane in system preferences. What it does is absolutely genius though. You can select any program that you have installed, and assign any gesture, and even 2 that aren't "official".

Currently I have it set up on Firefox 3 Beta 5 and I have swipe right mapped to cmd+] (Forward), swipe left mapped to cmd+[ (Back), swipe up mapped to fn+up (Page Up which changes tabs), swipe down mapped to fn+down (Page Down which changes tabs), rotate right mapped to fn+f5 (refresh), rotate left mapped to fn+left (Home which goes to top of page), zoom out mapped to cmd+w (Closes tab or window), and zoom in mapped to cmd+n (open new window).

Anyway, after using this program for just a day and only mapped to Firefox, I am completely hooked! Just to tell you how much I love this program, I have already donated to him, and I strongly encourage you to also, so we can see more updates to this!

A few things that I would really like to see done to this: I would love to see it work in Carbon Apps (Like Finder); I would love for it to have better capturing of the shortcuts (It doesn't capture cmd+tab or my shortcut key for quicksilver [cmd+1]); I would also love to see a little icon up by the clock to quick set some short cuts for the active window (even though this isn't big).

4 out 5 stars, with an easy 5 if the first two things are fixed!
