I’m liking the new look and you’ve done a great job with it David. I’m assuming with the absence of a separate category for latest images that each tag will have the most recent images posted on top and they will progressively get older as you scroll down. It looks to me like that’s the way it is now, and that works well.
From the dropdown I use Categories the most because it covers everything in one view. Everything else is subcategories. Sometimes I don’t want to search individual subcategories via separate dropdowns. It’s important to provide a Birdseye view of the entire site from somewhere.
