more functionality to watched sessions?

it would be nice if there was an option for watched sessions to be pinned to the top of catalog view! or if that messes with the flow of everything, having watched sessions be highlighted/colored differently compared to the rest would make picking them out while scrolling way easier. I already hide sessions I won't be able to join, but as the site gets more popular it'd make tracking what sessions are when more manageable at a glance.
