@eht16 it works now,
Great, thanks for testing.
but maybe it's abit not that convenient if compare with project organizer because have to manually click to refresh
That's a whole another story :). The TreeBrowser plugin is rather old and not really maintained (while I worked on this and the other issue, I won't implement new features or change its behavior, I don't even use the plugin). So, either just use the ProjectOrganizer plugin or open a new issue for the change in behavior.
