It's already been suggested up there but I'm repeating because that very same thought crossed my mind over the week-end, a Holidays/Seasonal category would be nice.
For Tutorials, I would love some kind of "general" or "drawing" category for those tutorials that can apply to both digital and traditional art. ie, for tutorials on anatomy, colour theory, composition (which can also be used for photography too, I suppose), etc. that can be used for everything from pencil sketches to 3D models. I know there's a "miscellaneous" category, but it feels like those types of things don't really belong there, and generally can't be found there anyway.
Either Objects>Doors and Windows, or maybe do Places>Exterior>Doors and Windows and Places>Interior>Doors and Windows...because I have a problem with putting them in Objects...

I should've kept the plan Znow, LDD and I did so I could've passed it on. D: Oh well.
