As much as I tend to go for simpler-is-better, your ideas for .12 sound good to me. The only other thing I can think of is that when it successfully copies the selected text, maybe a little confirmation window -- something like Clipped! -- could flash briefly. (It's more important to flash a window when there's nothing to clip, and you've already implemented that. But I still find I go and look just to make sure the clipping happened. "Clipped!" would alleviate that paranoia.) If you got really ambitious, there could be a setting where anything clipped from a browser automatically was followed with the URL. But that's probably a lot harder to implement.
