Yes, I have EDSM permanently running in a separate window on a second monitor because this is easier than constantly switching to the in-game map for data on planets I have just scanned. It would be nice if this facility existed in-game. If the planet is landable, you cannot even get the information on the type of body without switching to the map because the landing tell-tales overwrite it in the target info panel (as an aside, that should be toggleable).
