I love the Steam workshop, but it has one very irritating feature. I can't access the scenarios when offline! This is nonsense, as the game has to download the files from somewhere. Why not store them in the mission folder as usual?
Furthermore, we should be able to delete the missions with a button on the Scenarios menu, without having to open the Workshop.
The main thing is that Steam is awful as a web browser and opens very slowly. If connection is slow, it often doesn't open at all. So we need better offline capability.
