Today when I synchronize, it is very difficult to scroll through the categories, since these are Espand.
and for me it is a problem because I have over 20,000 categories and subcategories.
Synchronize currently as follows:

directories + files
Search in subcategories

----------------------------------
The opposite happens to me when I go for the option to manage categories, is quick visualization and navigation between them.
This is I guess that does not open in a tree, I propose that it be handled the same display used in category management for synchronization.

-------------------------------------------------- -----

SUMMARY: Changes the display of the categories of synchronization used by the administration of the categories, being faster and more effectively, to handle large volumes of information.

Beforehand so grateful for your attention.
