For my use case, I don't need to see all of my windows because I know exactly where they are already, having put them on a specific virtual desktop, tag or group.
I would like to know more about how to do this kind of thing. It would be nice to pop up a set of windows (e.g. editor, shell, browser) in the same place with the same content each time via some hot key or command. I've tried this in the (distant) past but I've never seen these ideas work well. How do you know exactly where your windows are?
Maybe cause they are WMs and not DEs? But yo should take a look at
x11-wm/skippy-xd to get exposé like behaviour.
I'm not understanding the relevance of the distinction. I have only found expose-like behavior to work as the result of using a specific window manager. I use the desktop environment Xfce currently with the window manager KWin (sigh) and I get the expose behavior I want. What am I missing?
Looking at the DE side, there's been an open
bug about this for some years and this bug even got turned into a
bounty at some point. If there was a DE other than Gnome or KDE that actually has this feature, I'd love to know about it. Otherwise, this might help illustrate why I resist the idea of looking at a DE for this feature (and why I'm crazy enough to use KWin and Xfce).
I did look at something called "skippy" several years ago and it wasn't usable, reliable, or fast for my use case. Looking at the github for skippy-xd, I see the last commit was almost 3 years ago. Looking at freshports it seems it was abandoned for 6 years but very recently someone has resurrected this port. So ... maybe?

I think I'd much prefer this functionality to be built into the window manager for performance sake, but since I'm not coding anything I'll use what is available.
