I suggest moving the New Category button up to the header where the Google button is.

I want to suggest you move the New Category button up to the header where the Google Drive and Support buttons are. Why? Because if you have a LOT of categories and subcategories, you have to scroll up to click the new button, then back down to work with the category. Putting the button in the header, which stays locked when you scroll the page, would make things a lot easier.

I'd also love to see a "collapse all" button near the top that would close all categories so the subs are hidden. Right now, every time I open the component I have to manually collapse all the levels so my list is short.

thanks!
