How to configure and adapt Aimeos based shops as developer
Forum rules: Always add your Aimeos and PHP version as well as your environment (Linux/Mac/Win)
There are no other themes that we currently know from. Maybe because everyone is adapting the Aimeos Elegance theme to their project and nobody had created another generic theme yet. A new theme should be distributed as Aimeos extension as it's easy to install and can contain everything (templates, CSS, JS and configuration) that is required to automatically active the theme.
