- Tweak positioning of old "working" spinner to center and align it
- Fix pagination to not enable the "next page" arrow when looking at a small, complete, filtered result - Move content table setup and drawing to a new method called on the main thread. Should improve thread safety, and fixes flickering updates. Tweak a few bits of drawing code to take advantage of main thread status to further reduce flicker and jumping
