Comfortable migration from GOG Galaxy

Transfer manually added games and tags from GOG Galaxy.

I know a lot of people who would be glad to switch GOG Galaxy to any good alternative, since Galaxy is terribly slow and unrelayable.

The launch box seems like a good alternative, but the thing that always stopped me is the fact that you can’t transfer manually added games and tags from GOG Galaxy. I have around 7000 manually added games on GOG (physical editions for different platforms and games I'm interested in, but haven't bought yet). So, it will take months to add them manually. Just the idea of manually adding thousands of games (and hundreds of thousands of tags) is killing me.

Also, the ability to group games by release year, as well as filterthem by tags is a must/
