Feature Request: Close/Minimize to tray

Loving Groupy, but while I love consolidating them to one taskbar entry, I would LOVE to further declutter it by moving it either exclusively to the system tray, or at least being able to close it to the tray so it disappears from the taskbar until I open it again.

This actually would be a really useful utility in general and would make a great addition to the Stardock suite, assuming it doesn't already exist?

Anyway, really could use this, because whenever I do close the tab group, they don't always regroup correctly, so running it once and keeping them collected and always running in the tray would be ideal!

thank you for your consideration!
