I am sure that the BTT feature set has grown over the years, and that BTT reflects those first abilities. But all these years later, I completely ignored BTT for the simple (and only) reason that I didn't think I owned any devices compatible with it, based on the name alone! I can't be the only one with that false impresssion, which BTT does not deserve.
Have you considered a name that makes it clear that a touch-capable device is not required? Even BTT's description on Macupdate.com merely says "Customize multi-touch trackpad gestures."
That makes it seem very limited, when nothing could be further from the truth!
It took reading about someone using it for keyboard macros in a random post that I stumbled across to even let me know it was something I could use, let alone an extremely worthy product.
While a name change would be painful, it could also bring more customers.
