I made an alternate version of the itch.io integration. One already exists and is on the list, but they have different functionality (I've talked with the dev and for now we'll be maintaining them separately). https://github.com/tauqua/gog-galaxy-itch.io
The existing one on the list is only able to recognize games currently installed through the itch.io app, while this one recognizes all in your library. However, this one currently can't handle downloading/installation while the existing one can.
IDK how you want to handle two separate plugins but here it is.
