Windows Explorer Breadcrumbs Drill Down

Hello Quizo,

I really appreciate QTTabBar so my comment here is regarding a feaure I would like to see added.
I understand that I can drill down on the breadcrumbs in the tabs itself and other places, but I think it would be really useful if we had the breadcrumbs drill down on Windows Explorer path itself, so one could drill down to the lowest level directory.

Thanks for the awesome work with QTTabBar.
