Instead of having a large bar across the top of my stream displaying all of my streamlabels, I would love if I could combine all of my streamlabels into one rotating streamlabel that sits underneath my webcam. This way, all of the information I would like to have displayed (I.E. Recent sub, follow, top donation, etc.) could be displayed in turn underneath me (or anywhere I decide to place it). I think it would also be awesome if we could get a few different animation types with this such as a fade in/fade out, text scroll, rotate, etc. This would allow people to display as much information about their stream without having to flood the screen with streamlabels.
EDIT: The way that the sponsor banner is set up in streamlabs would work perfectly for combining multiple streamlabels. You could set up whichever label you would like with the animated effect, show for a set amount of time which can be adjusted for every label, then place that on your stream. Basically reskin the sponsor banner and its done!
