Fantastic work on the Manual Cache tool. I have one big gripe. If I want to edit an already defined region, I need to delete it and start again. I would love an edit function that lets us change the quality zones.
If there is a technical limitation that means we cannot edit a region then create an edit button which starts the process of creating a new region, with the region name and boundaries pre-defined. Once the new region is saved, then delete the old one, clear out the old data and re-cache the area.
