Just noticed something interesting about #OpenBSD's #cwm:
As you alt-tab between windows, it snaps the mouse cursor back to where it was in that window before you switched away.
It basically emulates the idea that each window has its own mouse cursor, which is only visible when the window is active.
Not earth-shattering, but kinda cool! :)
Right, it's a very different model to what I'm used to (going back 39 years), but I don't dislike it!
@RL_Dane I'm not even sure that I like this particular mouse pointer concept, but I strive to think this way in my abstract designs.
