Andrew, please answer me this and consider for inclusion!

With photos - or more specifically Videos (writing here as no video note yet!) - please consider the option to create Categories, and then sub-categories instead of just cats...

This for Videos makes things much better for user navigation.

For example, with sub cats, I could list cats as A,B,C,D,E,F... etc
then have sub cats for things like Bands names alphabetically under each Cat.

It makes things much more user friendly when see more there is need to separate things more.

Please consider this, especially for Videos!

Thanks :-)
