I love using (tiling) window managers, and one of the most important requirements for me is having a key binding for switching to the last active workspace. The proposed solution in the blog doesn't achieve this. I use Aerospace on macOS right now and think it's the best solution available.

I generally have fixed workspaces for different things: first for a browser, second for a code editor, third for a terminal, and so on. If I want to switch between the browser and code editor, I can do that with a single key binding, usually Alt+Tab. The same binding lets me switch between the code editor and terminal just as easily.

When you have something like 10 different workspaces, not having this key binding becomes annoying. If you need to alternate between windows on workspace one and workspace eight, you're stuck using both hands to press Control+1 and then Control+8. But with a last-active-workspace key binding, you can just Alt+Tab between them. This is the killer feature I always need.
