Comments will not cancel a snooze event
A lot of teams have a workflow where they snooze a conversation and continue to comment on it. It can be frustrating for them to always have to click Snooze again when it was internal comments that broke the snooze rather than a message from the client.
An alternate but similar idea would be to have a "Hard Snooze", where something snoozes for the time period you enter, regardless of a comment or a new reply.
Critical feature. Boomerang, a gmail add on has this and it works brilliantly. They have return message if no reply/comment, or by default no matter what with a simple check mark.
