I've added a shortcut for some user interaction by hovering your cursor over a username in the post:

You can go to chat, follow, (soon) tip, (soon) ignore.  Hover the icons for their functions.

It's just the first roll-out of this feature so it will be improving/changing over time.

I also added more for groups:

You get information on the group level, the number of posts, users, and (soon) a subscription status/link.

I'm adding this as a "quality of life" feature, and it's not completely done.  What do you think? Leave a comment.
