Thought I'd share my Zenfolio site with the community. I've done as much customisation as is allowed by Zen. But there are some areas which are locked down such as the gallery caption which has frustratingly basic formatting tools. However I've made full use of being able to tinker with things like the welcome message on the home page.
I really like Zenfolio because of the built in blog and the Lightroom plugin but have to say I hang my head in disbelief at how poor the print sales section is. It's a real mess and hides all my menus and branding which is so confusing for clients. Fingers crossed that when they've got SSL sorted out the Shop and Quick Shop will get fixed.
