Some time ago, in Flexibase3.0, I had the concept of 'plugins' or 'components' for themes. The idea behind it was to create some of the features of flexibase (often popular features taken from other themes) in such a way that they could be (fairly) easily added into other themes.
I dropped this from flexibase because of the increased complexity of having them in the theme itself, but did promise at the time to make them available in a separate repository. With the comments surrounding the work I've done with Chris recently (radial grade display and completion and the featured/tagged courses slider) I have now created that repository
In the first place, the components are the ones I had in FB3.0 - Alerts, Marketing, Social and Awesomebar.
The more recent radial components and course slider will be added in a week or two.
I hope people find it a useful resource for their own themes - particularly people who may have access to their theme code, but are not necessarily developers who would be able to integrate these features in more standard fashion as part of their theme.
