Yeah I looked at spaces but it didn't seem to work for me. I couldn't set it up with my local bridges the way I want. And I don't want to micromanage everything.
The old tags worked very well for this but the problem is that element shows each tag as its own independently scrolling list. So if you have many of them you have lots of tiny scroll zones. That doesn't work at all. Also they seem to be wanting to deprecate tags, most of the management features have been removed from element.
