Option to hide folders with "zero" unread items from "gg" bar (or list them at the end).

I have been great fan of "gg" bar to instantly navigate to some folder.
Typically the way I read my feed is, go from one folder to another (i have more than 10 folders numbered per my preference so they list one after another)

So, once I finish with reading all feeds from one folder, I move to next folder using "gg" or left sidebar. Left sidebar intelligently hides the folders with zero unread items and lists only the ones with one or more unread articles. But "gg" bar (which is good for keyboard junkie like me! I use that more than left sidebar which is accessible only from mouse) lists all the folders (even those with zero unread count). It would be really nice to list them at the end OR provide an option to hide folders with zero unread articles from "gg" bar.

Let me know if I am not clear.
