The too many comments autoflag now has a special button to move comments to chat (yay!):
Can this button please be made to dismiss the flag?
This has been a minor annoyance for years since we need to first move and then go back and dismiss the flag. The action of moving should automatically dismiss the flag as helpful.
I assume that the reason the button still appears when I revisit the page after having moved the comments is that checking that the comments have been moved requires some sort of lookup and that would slow things down. I get a warning if I try to move them again, so that's fine. But it would be really nice if I could handle this with a single click that both moves the comments and dismisses the flag.
