This is my driver since it become usable. I have 140 terminals on 2 workspaces. Grouped by project/task. I know, I'm the author, so I'm biased, but I love working using it.
I kept macOS surface isolated and constrained on purpose (and also have my own rendering engine) so it should be rather easy to make it run on Linux. The biggest obstacle is that it's hard for me to test (I have a gaming rig on Linux, but I don't use it often lately..).
