I think Mangowm and maybe even base dwl have a feature like this, where it shows you windows from other workspaces as well in an overview and you can switch between them, but not entirely sure because i personally don't use it much aside from trying it once or twice.

How many windows do you usually have open in a workspace? Wouldn’t the usual Meta+Direction shortcuts be quick enough for 2-4 windows?

Have you tried "niri" wm? Pair it with dankmaterialshell or noctalia-shell for a desktop feeling (cosmic is also and option.)

The keyboard based control you are looking for is almost met, but not quite. That said, you might find this kind of a navigational wm works well for you, based on your description.

The niri website has a decent video demo.

Idk if I follow. I believe the default keybinds in hyprland allow you to switch between windows using super+J/K/L/;, and between workspaces using super+number. Hyprland, like all tiled window managers, are specifically designed to be used exclusively with a keyboard.

Are you asking for something more like alt+tab on windows? Where it shows a little preview of all the windows? I think that's kind of obviated by the concept of a tiled window manager.

Try sway. It's great and just works.

Sway. Windows manager, switcher... all that. Fully keyboard controlled. You can change any key combination you don't like. :)

So this is not exactly what you want, but have you seen the rofi -show window feature? There's no preview of the window, but it does display the title even if the window is not on the current workspace.

I don’t know if I understood correctly but I have seen this maybe this helps:

You can switcj windows using keyvoard with apps like krunner, rofi, etc. Not exactly what you described/wanted.

I like rofi for this use case, but it uses fuzzy search instead of labels. You might have to type more than one letter, depending on what windows you have open. OTOH if you know any part of the window title you can start typing immediately without having to scan a list for a label first.

Labels work well for jumping to something you can already see, because the label appears where you are already looking, so you see it immediately. I'm guessing the process of finding the label for a window that is not visible would be clunkier - you'd have to find the label in a possibly long window list.

I think you want something similar to my setup... I rarely position and focus windows with the mouse.. only for certain apps that don't resize well into my predefined regions. I believe it's somewhat similar to what Rectangle can do on OS/X, although I only stumbled upon that later.

Here's something I put together for the (not-hyperland) compositor LabWC: https://github.com/labwc/labwc/issues/1001 (and have done similar with X11/OpenBox previously) which might serve as explanation and inspiration. Your post inspired me to rebase and clean up the patch, so thanks.
