For the group warning, if I’m a member of the group, ideally we dispose off the warning completely. Possibly one could set a threshold, so if you are going to notify over N folks, that’s when the warning gets triggered.
I think for auto timeout, the timeout duration could be configurable. Most of the times, it isn’t as useful. But when it is, it’s very quickly obvious. Typically the first result is the right topic. But it’s def a distraction when composing the post, all the time.
