Please add a bubble level tool

[bee67]

Hi, what exactly do you mean by “level things” (perhaps a translation issue? I could try to push my knowledge of French to its limits)…

Thanks for taking the time to reply, and sorry for my French!
A bubble level tool would be great in the section "everyday life" (eg: Bubble Level - Apps on Google Play) . (It would help to indicate whether a surface is horizontal (level) or vertical (plumb). 

It doesn't sound easy to code, but much easier than the tools you provide in your awesome app.
