Hi
It's not written in the widget to snap to the top of the screen (tested it right now), so I assume you have snap to grid activated with some high value (maybe).
There wont be a gui for configuration.We try to keep the application as small as possible and it's easy changing the values in the file. We have 5 config files right now and I don't think you are changing the properties that often.
I don't like to use the stylus for these things. Nevertheless I plan making all / most of the gui elements configurable. Right now I have to do some other work, so electroaudio can continue his.
