Replying to Highlighting people's posts

Hey so is there any chance we could have a feature where we have a list, perhaps our "friends" list, and any time you look at a thread any posts by those people would be highlighted for you?

idk shit about coding and whatnot so if it's a pain in the ass it obviously wouldn't be worth it. but that'd be a sweet feature. some of the best posters on the site who actually offer great input and info don't have icons and you can miss them easily

just an idea
