hey, i tried it on ios9 with iphone5. yes on the first try I had to double tap on a project thumbnail after the thumbnail was shown. afterwards it worked normally. hmm will look into this further.
The controls for project thumbs should show up in the customizer when you navigate to a category in the customizer. If your frontpage is a category, you should see the "featured image" and "project title" controls.
"/categories/projects". Would prefer just "/projects" if possible.
