What problem are you trying to solve with Submitty
Right now, if someone sends something in a live chat that needs to be deleted, the whole live chat must be deleted. A better solution would be to either add a live chat clear button, or a button to delete individual messages (or both).

Describe the way you'd like to solve this problem
For a clear button on the chatroom list, we should add an icon next to edit and delete, and for individual messages we should add an icon next to each message that appears on hover.
