Bundled Add-on Spectrum API
Three of our plugins: Ideation, Glossary and Discussion came bundled with an add-on called "Spectrum API".
We created this add-on to provide a common platform to our products and ensure license management. It's also a fantastic way for our company to reuse code and ensure a great source code quality for our products.
Disabling or uninstalling this add-on causes the stopping of our add-ons listed above. You have to keep this bundled add-on in order to have the main add-on working perfectly.
Spectrum-API add-on can be identified by the logo above
