By now my GoG library / collection is a little confusing - unfortunately I can't take notes. So from time to time I want to go to a game description after clicking a game in my purchased games library / collection but all I get are the installation-files. ;(

Is there a clue I've missed?

I've not tried it myself but I believe you have the option to also tag your games with your own descriptions. Not an answer to your question but I wanted to point it out.

Ah! Thanks! :D Thanks. I use this already. That is at least something but not a good solution....

You said taking notes so I thought maybe you were noting which ones you had downloaded, which ones needed to be downloaded, etc.

I'm glad LexRoost was able to help you.

No Problem. I appreciate your willing to help. :)
