Rescan button needs to be somewhere else
I lost so many scans this week because it's right under the stop button. I would either accidentally double-tap and trigger a rescan, or the scanner would automatically end scanning just before my finger touched the stop button, so I would press rescan.
* move the buttons so that the stop button can never be at the same place as the rescan button. (Horizontal button layout, move stop to the top, make "rescan" the top option.)
* Put in a short delay before the upload/upload later/rescan buttons can be pressed.
* Something else?
