Is there an Electron / Framework7 example available?
You can easily create one unsung framework7-cli
Yes, but I end up with an iphone style page where the toolbar is on the bottom (desktop is usually on the side or maybe top). In the medium announcement of the desktop theme, there were some great screenshots, but no code.
In that blog post there is a link to repository with those layouts https://github.com/framework7io/framework7-recipes
