I recently had an answer deleted. I also got a comment, saying:
(...) You can improve it by following the guidelines mentioned [here]. Feel free to flag it for review for undeletion once you've done so.
There are four buttons under my answer:
flag but it's not obvious which one to press to flag for review for undeletion since two buttons have those words.
undelete might mean undelete without review, while pressing
flag when there's an undelete-button right next to it feels wrong. If this is a stock comment, maybe clarify that.
