Ability to manage achievements.

Some games which are cracked don’t offer steam tracking for achievements using the launcher even though they are steam games, especially with games cracked by Empress for example. Therefore adding the ability to remove/add achievements would be beneficial. Since you guys already added the ability to alter playtime I think this feature would be even better, you could also do the same thing done with the playtime where it displays a message telling everyone that the trophies have been manually added. E.G at bottom of that and a game which I cant track achievements for.
