2 requests: First, the ability to import runes from screenshots at end of dungeon (detecting center). Example, you just got a tune in dragons and could snap a screenshot rather than having to dig through your inventory to find it. This would be huge. Hands down this would be the biggest and most convent upgrade. Second, ability to reset your runes. Right now you have to uninstall and reinstall to do so.
One other suggestion would be a duplicate detector in case you're accidentally importing a rune twice.
There's some text recognition to be improved but folks, if ou ever took a month to manually input all your runes looking at your device and typing them into the optimizer, this is a million times better.
