ControllerMate

I've seen here and there posts asking about how to change the behaviour of input devices such as keyboards, mice, tablets, trackballs, etc. and I found this in my bookmarks, OrderedBytes' ControllerMate.

I was simply wondering if anyone here had ever tried it and if so, what were the thoughts and impressions on the ease of use of the driver/controller.

Could this could fit the bill for anyone wanting to change or adding functionality to input devices on a Mac?...

haven't seen it, but may have to bookmark it for future reference...
