The ability for user's create their own modules or addons without having any programming knowledge is great! Also adding new features can really help your business grow faster than you think it will! I'd love if there was more documentation available in how things work so that we could implement them ourselves instead relying solely upon support from developers at this point (we're still learning). We've been able to increase our revenue by creating different content types within one product category which has helped us differentiate between products better as well.
