Better Message Edit

How about a change in the Chat Edit?

When you go and edit your Message, the "Layer" minimize itself so you need to scroll to the point, where you need to fix something or want something to add and yea, it's kinda annoying.
It would be very nice, if you go to the Edit mode, that the "Layer" don't minimize, so you have a better overview to your Message, mainly if the Message is Big. Like you wrote big Rules in one Message, or an explanation. So, a bigger Layer would be very good.
