Feature request: More precise values for leveling tool

[surprise-jpeg]

I'd like to get an option in the settings for the level tool to have more precise values. Currently it doesn't show any decimals. Even when it is on 0°, there is a slight tilt.

Part of the reason it doesn't is that phone sensors aren't super accurate. Showing decimals might create false impression of accuracy.

Could it still be implemented as a toggle in the apps settings even if it isn't precise?
