I am running Macs for over 20 years now and I wonder: why do we need Dock at all? I have hidden it over a decade ago and never ever used it. If anything, it gets in the way when I push the cursor to the edge of the screen.
(I exclusively use cmd-tab, which is a Docker feature)
I leave it there because I have a large screen and it looks pretty
I think that's fair.
My use case is fairly simple: I usually have multiple VS Code windows open at the same time and I have a habit of moving windows related to a certain task to a specific space. The default Dock mixes every window up and I just want to offload the which-window-is-where tracking to some other app - in this case boringBar.
