With the recent addition of external libraries (OPDS), we now have nested folders in Panels. That makes navigating through your collection a bit less convenient.
In the next version of Panels, we are adding “Favorites”. You can create a favorite link in the new content browser and directly access the folder you want.
This will also be quite handy when we release the local library nested collections support (yes, we are still working on it)
Favorites already support Local and remote libraries.
