Since the building levels quest was redesigned (I believe using Compose?), the keyboard automatically opens to input numbers, but I don't think that's how it used to be. My muscle memory is to hit the recently used levels buttons and then the checkmark button near the bottom of the screen, and now it's halfway up.

Other quests that require input (address numbers, heights, number of bicycles, etc.) do not auto-open the keyboard, which is interesting because you have to type in these. But the building levels quest is for me usually inputting recent values, not adding new ones, so the keyboard is intrusive.
