Pablo,
This is probobly more a request/suggestion but i wanted to ask You is there a way to build a site in WWB using only relative units (percentages, vh&vw) for layers, fonts, spaces between them and other objects? Right now it seems to be implemented only for some elements and even then somehow limited (e.g. layout grid column height can be set to 50vh or 100vh but no "custom vh".

I'm sorry, this will not be possible. All sizes are in pixels.

Any chance to implement this in future?

This would require a complete redesign software so this functionality will not be available in the near future.
Also, I am not sure if many users will find this useful.

It's a pity. It would be usefull in what I do in WWB.
Of course I understand that You have better insight into other users needs and requests.
But, perhabs other users could kindly speak up, if they find implementing relative units would be useful for them too.

Bests
