We have decided - at least for the moment - to keep the RibbonLib - and the other modules of the MapBasic Common Library - as a separate thing at the moment.
By not distributing the modules with MapBasic but having them on github.com, we can more quickly make changes and fix issues with the modules.
Consider these modules as "open source". Anyone is welcome to contribute to the modules either in the form of code or simply by raising requests for new features or functions using the github platform.
