I came up with some more questions:
1. Is it possible to use a different menu on different pages or do I need to use a plugin like zen menu logic?
2. Can I disable the sidebar on certain pages?
3. Does the theme come with the German language file?
4. Is it possible to self host google fonts and do you provide support for this?
5. If I purchase a licence for one site and then decide I want unlimited, can I upgrade the licence and then just pay that amount or do I still have to continue paying for 1 site + unlimited sites?
