Yeah, I do know that. What I don't like about alt+tab is that it doesn't respect virtual workspaces. I use workspaces to group windows I'm working on at a particular moment, but alt+tab shows applications across all workspaces, and switches between those. Might as well not even have workspaces with this behavior.
It seems that everyone has their own opinion of how alt+tab should work. Personally, I have the AlternateTab extension[0] installed, which has a configuration option to allow switching between windows within a single workspace, rather than across all workspaces. There's also several other similar extensions, each implementing their own behaviour depending on what you want.
