Yes, that's right. The "left" folder can be expanded to the
"right panel" if its icon is marked with "+". Well it is some
feature of the "ROOT" Explorer. And I can not agree "this the
behavior quite inconsistant" as you said.

To implement what we are speaking about the program needs to know
in advance about the coming structure. It may slow down Browser
significantly for the large (huge) and complex data-set. Anyway this
could be changed.

Excuse me I didn't understand this.
There is no "+" on the "right hand" panel at all. And I found no
problem here.
Clicking the "folder" icon on the "right hand" panel does explore
this folder and does change its icon on the "left hand" panel from
"close" to "open" state too.
Double clicking the the "close" folder marked with "+" on the
"left hand" panel does change its state from "close" to "open" and
present its contents with "right hand" one as well.
