I want to report that on my phone the quick menu is difficult to use. From what I can tell from developing my FVN, RenPy think my phone is a tablet, and therefore uses the mobile() variant (UI gets rearranged), but not the small() variant (which is where the resizes occur). As a result, it is very difficult to touch small buttons located at the very edge of the screen. I don't know how easy it will be to remedy this, but I want to bring it to your attention.
