This is not a review as such.
We are looking for a theme for Moodle 3.0 to do an upgrade in January 2016. I've found it really difficult to do a good analysis as often I'm not sure what is a feature or a bug, I'm not really very good at CSS tweaks etc. But I did install this theme, and had a look at it. I think it has a lot going for it.
- Great styling
- Remarkable use of images in badging courses at the course level
- Images in tiling for each course on the front page
- Nice tabbed sections on the front page.
- Font Awesome based menus.
- ability to narrow header . . .
Chris done well in the plugin page with the videos and pictures so you should be able to get a good idea to see if you want to crash test the theme.
