I think this could be really useful.
The problem with the patching grid, is only a portion of the available points are visible at one time, so you can spend a fair amount of time scrolling. If you have something patched well up in the channels and don’t remember where, it can be a where’s waldo sort of search.
So, my suggestion is an overview screen of the fully zoomed out grid. It could be accessed by double tapping the patch button (for instance). Then the view zooms out to show the entire set of available patches (admittedly tiny). You then tap on the hunted tiny patch, and it zooms in to that area full size.
If there are no patches, double tap the patch button again to return to the ‘home’ grid.
This gets you to any patch in basically two clicks, instead of a bunch of swipes.
