Thanks @LoicPoullain , that looks great

can you sign the CLA please? I can't merge without it

[LoicPoullain]

Hmm, this is weird. I signed it 10-15minutes. I'll try again.

[LoicPoullain]

I've signed again. Maybe there's a lot of traffic now.

If you already submitted a pull request before signing the CLA, then we will add a confirmation comment on that pull request (this might take several minutes).

[slorber]
