I try to install on fresh Plone 5.0 (5011) installation: it does't work.
Nice theme, but the css drop rules, if you change something in the portal_css grouping, can lead to strange results.
I am just trying it on an homemade webserver before implementing on my site.
I find it is an actual improvement from the basic Sunburst Plone style, with improved functionality. Also the rendering on mobile devices even with 3" displays is great.
