It would be nice if there were a way for a similar edit to be made to more than one section of a song in a less-noisy way (e.g. not creating multiple comments or sending multiple email notifications), particularly when a tab has 3+ sections.
Initially I was imagining some way of submitting the multiple edits as a single atomic unit, but that seems potentially pretty difficult to integrate; a simpler approach might be, if an edit is made with the exact same summary (by the same user, within X minutes, with no other intervening edits) as a previous one, combine them in the comment view, and don’t send an extra email notification. The edit interface could also maybe help users with this convention by suggesting the previous edit summary when editing another section of a song immediately after the first.
