The top-bar collapse button is gone?

Quick inquiry.

The new studio UI update is interesting and all, but I can’t help but be bothered by the absence of the small arrow button that would allow one to collapse the top section of the main interface. I can’t exactly remember where it was, but I gestured with red arrows in the attached image the general region it was once located in.

Does anyone know where this button went, or any alternatives? Or has Roblox just ditched it? As an animator, I found it really helpful to have the space of my whole monitor unoccupied by any UI when working and recording, and it’s kind of annoying to be forced into a horizontally slimmer resolution now. If anyone could provide any comment at all on the matter I’d be very grateful.

TL;DR: The collapse button for the top bar of the interface has vanished and its absence annoys me. Does anyone know an alternative?

It would appear that double-clicking one of the tab buttons (Home, Model, etc…) collapses the top UI. It’s not quite as spacious as before and the button is definitely superior, but this works.

I’ve marked this as a solution for now; if anyone has anything else to impart, this thread will remain open to comments for fourteen days.
