EX Show Variants on Collection

App did not remove the "Options" button as I thought it would, and simply put an "Add to Cart" button below it. It did show the variants separately. I decided that the app wasn't for me, and deleted it. In my theme (Dawn), deleting it did nothing -- the collection pages still showed it. Had to get the developer to remove it. Note that they work 8-5 weekdays only, on Pakistan time. Because I put the request in on Friday afternoon in the US, it wasn't until Monday morning that it got removed.
