Add option to remove (entire) on screen control overlay for android version. Options to remove individual touch controls aren't comprehensive (can't remove dpad, up/down arrows etc.) nor is there just a single toggle for all overlays (for whatever reason). Peripheral controllers and dedicated handhelds have been around for awhile now which render any on screen overlay redundant and distracting. Given the high level of nitty gritty you get with other settings, this seems like a major oversight.
