Thanks for the contribution !

Could you please add tests, the code is difficult to read without it...

[joostlek]

You can hide them in the overflow menu -> hide annotations

But it's a good way to add tests anyway

[joostlek]

There's a merge conflict. Also, I do agree that I think tests are almost a must have for a feature like this. WDYT?
