Love RBTray because it's so small & unobtrusive. I hope you are still developing it.
It would be best to be able to Minimise to Tray from Anywhere on the Minimise Button. There is no need to display the menu here because it been accessed anywhere on the Title Bar.
Maybe Pin on Top can be accessed by right clicking the Close button? But that's not as important my first request.
Thanks for your time.
