This is my vote to integrate the functions under the "Set {Seqn} variable..." button into the rename window itself. I almost always use 000 as the length. The only thing I need to do is reset the variable to zero, frequently. But it takes 3 mouse clicks, and a window to open. If the reset button for the variable was right on the main rename window it would be 1 click - and save me a little time and hassle. Plus if you put that on the the main rename window, you might was well just add the box for the variable itself, and get rid of the button all together.
Thanks,
