I love Vanilla as it removes pretty much all that annoys me with other forum software.
Except one thing. Announce clutter up the top of forums and force scrolling past them which is annoying.
Could it be possible to have an intermediate step between normal post and announce ones? We could call it "Important". Posts marked as Important will show up for every user at the top (like announce ones) until they are read. If you already read an Important it will have it's normal position depending on when it was last replied to.
This would permit to leave for instance guidance for new users without adding to the clutter for everyone.
