Auto Exit on Inactivity

[Swap-File]

In the last few days I've found myself looking at my phone an hour after using a barcode, and still seeing a barcode, since I forgot to exit Barcode Wallet.

Would it be possible to have a setting to automatically exit after 1, 5, 10, 30, or 60 minutes of inactivity?

Some other apps have this feature (myHomeControl), and I've found it very useful. By leaving it set to 5 minutes I never need to think about exiting the program. My watch is just back to being a watch the next time I look at it.

+1 also for this!

This feature is not needed for the widget version (it automatically stops after some delay due to builtin feature) but is a great idea the app version. I will have a look for that
