I think list of categories in upload area should be modified.
If someone have many categories/subcategories, finding all we must mark is quite complicated.
In my opinion best solution would be expandable tree with categories. But I’m aware it is lot of work to make such solution.
Maybe it would be simpler to change the structure of this list. Order is good but some indentation for subcategories could be very helpful. Maybe something looking like this its possible to make:
I try to add underscore sign (_) in front of subcategories but this don’t look too good:
Maybe someone have more ideas, or can help to improve this category list.
Like I said before, it would be very helpful. And if somone have lot of categories finding all is almost impossible.
Hope you endorse this idea.
