In Folder Tab I want Large icons.
I cant set icon size for Folder Tab on the tab name.

I can set icon size - right click on the part where is the content of the folder in the Tabbed Dock, and chose Large icons.

The problem is that after a reboot icon size go back to the default settings Medium icons.
Regular Tab / Taskbar Tab / System Tray Tab working OK save settings after restart.
ObjectDock is a nice job.
Regards!
