One thing I would like to do that I was never able to do in Radio efficiently would be to have two or three "custom" fields attached to each of my entries.  These fields would contain data like the music I was currently listening to (ala Livejournal), or my GPS position, etc.  While I find that I can add this data to the bottom of every post, or even add it to the keywords and put HTML in that field, neither flavor really provides me what i'm looking for, which is something abstracted from the posts but still able to be published in an integrated way.

Anyone have any ideas?
