I wish there were a way to make a quick, temporary code replacement in the caption window. I'm frequently dealing with names of subjects that I'm only going to use for that shoot, and I'd like a way to make a quick copy/paste into a sidebar in the caption window that would carry over between images without actually applying them to the caption to pull in when I need them. I think having a stationary pad-like pane with code options might be a good way to do it.
