Sorry, bit late to the party but I’ve done something that may help.
I’ve got a touch frame and I use the MMM-Modulebar to show/hide modules (the long list).
I’ve also copied the MMM-Modulebar folder and renamed any instances of the module name in any js and css files, copy called MMM-ModulebarHide, and now have a single button that shows/hide the list of modules.
The idea came from someone else in the forum, can’t remember the name but here’s a shout out to you.
