1. Lets say you own a "Gold edition" to a game, such as Anno 1404: Gold. That game actually comes with two games, Anno 1404 and Anno 1404: Venice. However, in this example, Anno 1404: Venice is not shown in the GOG Galaxy UI as you can only access the game through your Desktop which makes GOG Galaxy access to certain games impossible through the client. You were at least able to run the other games through GOG Galaxy 1.0 through the drop down menu.

2. I would like to have a feature where we can link any programm that isn't related to any Steam/GOG/any-other-client. Basically linking any "external" programm which is what Steam can do but GOG Galaxy 2.0 can't. Having such a feature in GOG Galaxy 2.0 would be amazing.
