Based on input from John I've put a preview of predictions on DynaKey as shown below. You can't interact with them only view them. One of my gripes with DynamicKeyboard is having to steer around that center area. Using predictions works the same way but now you have a preview. Work?
I've also been thinking of building my own equivalent to DynamicKeyboard. Although I think their idea is a piece of genius there are pieces of the implementation which I don't like. I think I can improve on it by allowing docking, transparency and some changes in usage. Is this something others would use?
