I browse for and buy a lot of templates in Themeforest, but I believe the current system is fundamentally flawed. The thumbnails are too small to see what the theme could look like, and hovering over the image can take some time for a larger image to appear (yes I have broadband). I find myself having to hover over EVERY thumbnail in order to get a better idea of what the theme could possibly look like.
Why not let us choose a basic and enlarged view where we could see a larger thumbnail like this by default:
http://3.s3.envato.com/files/18174958/01_Cover.__large_preview.jpg and perhaps even a screenshot or two http://2.s3.envato.com/files/18174958/03_DRAW_THE_SCREEN.jpg rather than seeing this image which does not fully represent what the theme could look like http://3.s3.envato.com/files/18174959/80x80.pngI would much rather browse through listings where I could see more of what the theme looks like. Third party blogs do this so I find myself going to them to search for themes, which seems a long way to go about it.
I have spent many hundreds of dollars with Envato, and if the search features were better, I’m sure I’d be spending a lot more than I currently do – I just get frustrated with the difficulty of finding anything.

Bu I also agree that users should be able to select the thumbnail size and/or other listing layouts, so +1
