this post was indeed helpful for that, and also as a recommendation for this game. :) but how do you open a game in edit mode? I don’t see a way to do that from the web interface, and I don’t know how to search for a specific game in the desktop app.
edit: never mind, found it! I was just browsing through the randomizer at the beginning of the app, I didn’t realize that if I go further into the edit screen I can also search the shared library from there.
