With Discord and Slack existing, why? Tell you what, if they do the following, I'll consider using it again in the future:
Add an option to allow for more than ~5 messages to appear on screen at once.
Add an option to stop the stupid fecking thing from ceasing scrolling when the 'last read' message hits the top of the screen (because, you know, some people have more than one monitor)
I lied, please go away, Skype.
