Could we get the green message indicator so it stays on until we have answered every PM?

I use the PM’s for conversations with other jellys, similar to a chat room, but privately. Right now if I check for messages every message is displayed in chronological order. But when I answer one message the light goes off, so if I’m not careful I might miss the earlier messages. If I’m PMing with more than one jelly at a time it gets tough to make sure I answer each message when more than one message comes through to me in rapid succession. Do any other jellys encounter this?
