(...) but like I suspected now BPIP quote copy option is missing when extension is used.
Hmm... that's a pity. (I've sent suchmoon a PM offering my help to fix it.)Nice! It's a pretty self-contained patch, so I was able to add it fairly easily. I left a warning on the post page, though, since I don't think it was otherwise obvious enough what was going on.
I think the warning you added was a good call. Thanks for merging this one! (That was quick. Of course, it had to be in the topic where I said "it's difficult to get theymos to come down from the mountain" that you merged it within a few hours of logging in.) 
Thanks for the kind words everyone! I'm always tempted to hit that +Merit button on every post that makes me smile, but I (mostly) always succeed in stopping myself: It just seems very self-serving to "encourage" posts like that, but you should all be aware that I appreciate reading them, and that they do mean a lot to me.
