I’m not sure the type of full width you’re talking about is what Fibery is talking about.
If you want it to be fully locked to full width and have no one in the workspace be able to change it (which I agree, would be nice!) then I don’t know if that’s coming.
I was more speaking to the annoying “jenga effect” we have now, where some things like relations and docs can be manually expanded to full width, whereas other things like rich tech fields are not expandable so users are awkwardly bouncing around between content that is misaligned with each other.
I’m not sure who was asking for “per field” width adjustment, but when I inquired about it at the time was told it’s because too many characters on a line is hard to read
