With plugins you can extend the functionality of KISSCMS, adding new features as they are required. Here are a number of officially supported plugins, hosted at Github:
This class will give you the option to save the data of a model as a SimpleDB item instead of using the default SQLite database. For now it is limited to just this function, although future versions may include support for other AWS products.
Supporting a series of services from the Google API and other useful titbits like automatic integration of Google Analytics on your website.
