Adding another little feature

So here I go, finally adding a little feature that's been kicking around for some time now. The first half of it is done, but it's the half that notices changes and reloads that still needs to be worked on. Oh, and then there is also the half of trying to figure out what to invoke, and the half of needing to deal with embedded images... Well... it's a start. Feedback on that bug would help get more things going.
