Making the other images for edit/reply, etc look like the new icons has been discussed in another thread on this board. It could be done, but I'm not much of an icon maker so I'm waiting for someone to come up with some ideas.
Adding the text to the post extras has been talked about as well. Currently it wouldn't take up too much space, but if we start adding more options down there it might. I know some admins/mods would like to have many of the post options for approving posts, moving posts, etc on the main post screen so these might get put down there eventually. So as we add more down there displaying the text along with them could end up taking alot of room.
