As far as I think envato themes are often not that, i often them often with clients on thing budget... they are cheap, ok support, and the bloating is shitty, yet useful.
a theme that give you 5 different header and 5 different post display has 25 different alternatives.
I need only one, but i can choose which one.

if someone will able to create a plugin which can reckognize the bloated code and strip it down to the only alternative I need... will get my money forever.
I don't know if it's technically possible... (for theme author I think it's)
