Thanks for a great work.
Can you add new feature (which could be optional and disabled by default) to Rbtray.
I am talking about windows minimizing (by clicking right or middle mouse button) not to a system tray, but to a special button/menu near system tray provided by RBTray. The one old and abandoned(non-working in modern OS) utility "Iconic Tray" had this great feature. Screenshot: http://www.iconictray.com/it_ss6_thumb.gif
I think that should be very useful feature. It can help to save a lot space in both system tray and taskbar.
