Is there a way to get LightPad to run in the bottom Launcher like on MacOS?
You can drag and drop the lightpad icon from the menu onto the plank dock.
That will run lightpad when you click the icon in the dock.
Every time I click to DRAG it opens up Lightpad before I can even Drag it to plank.
You can achieve the same via the application .desktop file found in /usr/share/applications via the file manager.
