I love the new tagging of our games, "completed, next to play, backlog, etc."

It would be nice feature to let friends also see our tags so they can keep up to date with our progress on our games playing library.

Also would be nice to get screenshot capabilities stream-line / built-in with the client then can screenshot completion of games for personal profile showcase.

This should go here: https://www.gog.com/wishlist

Then folks can vote on it.

This is the wrong answer. If the wishlist is to be bypassed, then there shouldn't even be a wishlist. Instead, everybody should be posting their suggestions on the general forum in the hopes that some staff "passes them on to the teams in charge of that kind of thing." And, since the spray of new posts buries topics in the general forum after a few days, and nobody bothers searching for old posts to necro, they should repeatedly post new topics every few days until their changes are implemented.
