I'm sorry, but this product is slow on my mT3G. I wish it wasn't, but it is. I notice it most if I call up a resource intensive app by using a gesture. I've got the animations turned off, and I run a fairly lean system. I don't think there is much more I can do to speed things up.
To put this in perspective, I have tried many of the home replacement programs (one at a time, of course, to keep the phone from slowing down) and there is only one that performs as well or better then the standard home screen - that's dxTop. But the screen to screen navigation on that app is too strange for me. Your navigation area at the bottom of the screen is excellent.
Today I turned on the swipe to unlock feature of my phone and you know, I think that is easier to use than the gestures in your app. It's more constrained, but that's not a bad thing. The dots on screen make it easy to remember patterns and easy to see if you are doing the pattern right. Did you consider just calling up that code from your app? The code is free and open source, right? Why not? I bet it would run a lot faster than what you have going on now. Certainly not as elegant, but perhaps good enough for the purpose, and seemingly a lot less processor intensive.
Despite the slowness, I will keep using Open Gestures for a while. I look forward to whatever you do to improve this product.
