A modified version of the Cinnamon window list applet that shows applications from all workspaces.
This is currently based on the window list shipped in Cinnamon 3.2.1.
Get the code:
mkdir -p HOME/.local/share/cinnamon/applets
git clone https://github.com/LawnGnome/cinnamon-window-list.git $HOME/.local/share/cinnamon/applets/[email protected]
Then enable it in the applet configuration and add it to a panel.
