Workspaces/Desktops thumbnails without gnome

I've been trying Openbox and other window managers this week. I'm quite happy and committed to leaving Gnome DE behind. There's one feature I'm missing though: I like the workspace preview popup that Gnome has by default. The virtual desktops thumbnails help me keep a stronger grasp on what windows are on which desktop. I looked around but couldn't find an alternative. > Maybe I lack the jargon? **Would you please, recommend me alternatives to the workspace preview popup independent on the Gnome shell?** Here's some links to posts with screenshots of the feature I'm looking for: - [Post 1](https://unix.stackexchange.com/questions/243760/showing-thumbnails-or-some-kind-of-preview-in-the-gnome-workspace-switcher-popup) - [Post 2](https://unix.stackexchange.com/questions/325256/how-to-change-style-of-gnome-3-workspace-switcher-dock-background) Keywords I tried searching online: - (Virtual workspace|workspace|desktop) (preview|thumbnail|miniature)
