Jonathan Gordon bb618dbd84 skin engine softlock support for touchscreens:
Modify the %Tl() tag to add a new region 'lock' which will lock/unlock the wps/sbs from touches (hardware buttons still work)
You can also specify a region to work when locked by prepending ^ to the action name (this is probably about to change though)
