I don’t know if this is the right place but its a suggestion after all so it might be.
I would like to have some kind of “this was postet since you last checked” or “this is new in the Forums you subscribed to” (this might already be there and I couldn’t find it. If so please tell me) and highlight these things. Just some Bigger Letters (is it called Bold?) For Forums where something new was posted would help me keep track of where to look for new posts.
Again if this is already in place please tell me I couldn’t find it.
