It would be nice to have the 'merit button' just like the trust one to open up the merit history of the user. I know all it takes is 2 additional clicks to achieve it, But it gets annoying when you are hunting for merit-sellers.
No, even for merit, you have the same number of clicks, you have to go a user's profile and then check for merit/trust. Only for sending your merits, its a quick pop-up. Also, in some sections, the trust button shows up below the avatar, and that is one click away from viewing any specific user's trust history.
