Is your feature request related to a problem? Please describe.
It's not always obvious which window is which based off the window title.

Describe the solution you'd like
The ability to enable window previews on hover of launcher icons, like Windows/KDE/GNOME are all capable of.

It looks like KDE does this via Pipewire, which is likely the best route to explore.

Describe alternatives you've considered
An easy/cheap way may be to use wlr screencopy or wlr DMA-BUF to grab a screenshot of a window whenever it comes into focus, or periodically while it's focused.

Hyprland offers a hyprland_toplevel_export protocol.

This is a long-term goal I've wanted since the beginning, but it probably still won't happen for a good while (unless anybody wants to pick this up :P)
