At the moment I don't know whether it is a bug with my version or it is not a feature yet but there's no way to click / right-click items in the System Tray. Having the ability to see items in System Tray is great but not having the option access/adjust their options kinda defeated the point. As of right now whenever I need to access the options of those items I need to disable Seleen to get normal taskbar back and then adjust the option in the default System tray.

Suggest Solution:
Implement the ability to click/right-click items in the System Tray (much like the behavior of default system tray)
