One thing I find confusing about the new site is that it's difficult to understand the scope of certain UI elements. That probably doesn't make sense, so I'll explain with an example.
Note the navigation bar on the home page. It's near the top of the page, so it's clear that it operates at global scope--it's going to show me all the journals, projects, etc. on the entire site. That makes perfect sense.
Now look at the bar when I or someone else views my showcase. It's below
Items by Ron Stewart, but it still operates at global scope and shows all of the projects, journals, etc. on the entire site. That makes no sense to me because of its location. Since it's below my items, I would expect it to operate at local scope and show just my projects, or my journals, or my reviews. (I guess it would be weird for me to have more than one workshop, but whatever...)
The same is true for the Filters dropdown menu that's just underneath the navigation bar. Maybe I can use that to show just my projects, for example. Nope, it still operates at global scope. Okay, what if I enter my name into the Created By field in the filter (and Projects as the prefix)? That stops showing all of the sites projects, but it shows just one of mine.
If UI elements are going to operate at global scope, I think it would be better if they appeared near the top of the page. I still think there should be an easy way to see just a member's reviews or projects. (I'm guessing there's a way to do it with a search, but why should that be necessary?)
