hm... not fully more useful, I also tried estouchy (which had to be tweaked manually for the resolution, because with default settings it did not start at all with my touchscreen). But the problem reported is exactly the same. And this is true for every menu which has no bars to scroll up/down. I assume all the skins are not made for resistive touchscreens, but only for capacitive touchscreens.
Anyway, a workaround is to reduce the main menu points and the configs can be done once via keyboard.
