Hi Ernie,
Bug alert.
1. Activate "personal hotspot"
2. Click on a deck. You're shown the deck summary page (e.g. 3 cards are due. Pending / New: 0 etc)
3. Tap on the top of your screen to show the deck name. It is mostly obscured by the Personal Hotspot banner.
It would be good if you could move this down a little like you have in the page listing all the decks. The main issue with this bug for me is when I complete my reps and try to move back a deck, I press the Personal Hotspot banner and get whisked away to the Settings screen.
A similar issue occurs when editing a deck. "List View Mode Filter" are partially obscured down the bottom of the screen.
Hope this isn't too hard to fix.
Cheers,
Dougal
