I've just added another text field that controls the number of clicks before the clicks automatically stop. In toggle mode, you have to toggle it again before it resumes a new set of clicks. In press mode, you have to let go of the trigger and press it again.
Please note that this program was never meant to be scaleable or extensible. It's really just a hack to get lots of clicks simulated on a windows machine. Therefore, all development is strictly based on feature requests and bug reports from users.
