When one selects text and clicks “quote reply”, it leaves the cursor right after the closing bracket. This is highly annoying when selecting a bunch of pieces of text to reply to (as one is encouraged to by the awesome “Hey, rather than making a million replies, you could, you know, do them all in one message” prompt).
Sticking a couple extra returns in would save a bunch of fiddly find-the-bracks-and-press-return-so-I-can-write-a-reply-ing.
