Ooh, I'm sorry I'm late.
Thank you for the 2D section addition! I think it will be great!
You asked if there was something to add. I think the categories are very good, and if something's missing, we still have the "other" category.
But I would add more formats, or at least an "other" format, since there are many 2D add-ons and other things that will not be just images. See the categories, for instance: actions for Photoshop will come in .atn format. Brushes, in .abr. Fonts and dingbats in .ttf or opentype. Gradients... well, it depends on which software they're for. Icons could be .ico besides .png. Tubes for PSP use a proprietary format. Vectors come in many different formats such as EPS, SVG, AI, etc.
See what I mean? So, at least we need "other" as a format option.
Thanks again!
