I like what there is so far, and recognize it's early days. Two specific requests:
1. Allow a full-width header image. I use one for branding. FJ forces my image to maybe 30% of the screen, which doesn't give the same effect.
2. Have an option for descriptive menus such as in Graphene. It's hard to find a theme that does this well.
My ideal would be the following:
a. header bar with site tagline and social icons
b. full width header image
c. descriptive menu
on scroll, this would all collapse to a sticky menu with a logo on the left and non-descriptive menu on the right. The Enlightenment theme does something like this, and the Awesome Sticky Header plugin accomplishes some of the effect. It would be nice to have it all in one theme, though.
