Envato has nothing to do with your copyright on items, you own your items so if you sell your account to someone then you are selling your items to him, and you are transfering your copyright to him, I think you just need to write a legal copyright transfer agreement between you and him just to protect him from any future confilcts that may occur!
Amazing achievement! congrats
I do like seeing all the marketplaces at once for clear and instant navigation, but I have to agree that there’s just too much going on up there now… especially when there’s a bundle announcement. It reminds me of IE on XP with a bunch of toolbars installed.
Having said that, and seeing others attempting to showcase alternatives… here’s a go at it.
Yup that is how it should be done, I like your design much better!
For me too much menus/tabs, nested navigation and crowded UI.
