I find the stacking of vertical UI elements to be a tad inefficient and has quite a usage impact, especially when I'm using it on a laptop. In addition to the title bar and file menus, there is the connection tab when a session is open which cannot be moved out of the way.
This makes it difficult when using a laptop resolution of say 1400*900 and trying to connect to RDP sessions at 1024*768. It can be done by hiding/moving the taskbar and going full screen but this impacts workflow.
Could an option be added to hide or move this element in a future release.
*Edited as notification and session tabs can be disabled.
