Hey raf,
while administrating multiple remote PCs (all in fullscreen mode; switching between them with 4-finger-swipe) I grasp the idea that Remoter for Mac could display the session title for a few seconds when switching to a fullscreen session. It could be an overlay banner in the top which is semi-transparent showing the title and maybe additional information (IP address, Group, protocol).
I understand that there are more important issues and features to be looked for. (mentioned bugs, file transfers, ...) I just wanted to write the idea down
