Hi @brc-dd , May I ask when you plan to merge this commit, because I need this feature very much in the future version.
: )

Ah, sorry. Slipped my notice. Looks good. I'll check the styles once maybe (grid-related styles aren't needed?) and merge it before next minor release. Also, can you rebase it to resolve conflicts? That should trigger a preview release now, which you can use in meanwhile.

Hey, our team could really use this feature! Is there any way I can help to promote its release?
