well, i found for me that it’s to hard to define format of source file.
for example: there is a item in the Graphics › Backgrounds › Abstract category. what kind of file type includes the item package? .ai, .psd, .png or may be jpeg?
i think the files formats should be define more clearly =)
Agree on that. Format of source file should be visible in the description of the product.
Agree on that. But I remind You that this is BETA so I expect some improvements before official release. Also Screenshot button would be nice to preview graphics.
