The Sections area, Templates area etc. should have a list VIEW option that lists all the sections, plugins, etc. in a list view rather than just the standard icon view.
It would be a lot easier to quickly browse the list and get info beyond just the pictures/price/name without having to click something first. You could easily fit Name, Price, Short Description, Demo, Buy buttons in one row. This way can check the list out, click demo on multiple items and then check them all out without all the clicking.
I think you'll sell more sections/plugins if there was a list view option. I find the thumbnails distracting and annoying as they don't give me much info since they're too small to show me anything significant.
