This revamp seems to have missed the topic timer I use most on my Discourse for Teams site - the auto-delete replies topic timer. This is amazingly handy for topics devoted to recurring meetings or procedures/documentation where you want to coordinate in the immediate term but don’t want to keep the replies forever.
I also noticed the “auto-close topic after last post” also has not been updated. It also has a fairly scary functioning in that it sets the timer immediately and warns the topic will be closed momentarily, even before you choose to set the timer. If you
X to leave the popup, the timer is already in place and the post will be closed. To prevent this, I reopened the topic timer, switched to a different timer which causes the timer to be removed, then
X to leave the popup.
