You're more of a workspace user than I, ironically - considering how much I mentioned them! I use the
tabbed layout, the lazy way out of many-workspaces.
I generally keep one workspace:display (three). Then splitting vertically/horizontally as needed. I use tabs as most would use workspaces
Left-most is a monitor with portrait layout, meant mostly for long-form reading. That's where Slack and other infinitely-going things go. This is WS #3
Center display/workspace is WS #1, unmapped things go here. It's a 4K display, I never share it - so it's a nice catch all for potentially-sensitive things.
Right-most is WS #2 - this is what I share, and is more 'the backup' for the primary. Things I do want to share are designated to go here
There's a lot of organization I did for 'autostarts', assignments, and shortcuts - that are kind of hard to explain... but easier to show
