No you're not the only one. It takes ages to load, and it's very disorganised now (my portfolio, I mean).
I was about to suggest the very same thing.
But with some other ideas too.
I'd also like to see a new category of "Man-made" in the list of categories you can pick on upload. And to be able to add my items in the portfolio to such a category (where appropriate) - since I'm never too sure where to put concrete, bricks or roof tiles... they aren't rock, or natural, nor are they really landscape.
It would also be nice if we could have a small image at the top of each folder or category - perhaps showing a selection of what's in each section? Like a contact sheet.
