The possibility to have add or view hints right from the main menu of the backend would require a substantial modification of the WebsiteBaker core. Addons are supported for cintent of sections, for adding support of a specific language, for backend and frontend templates (only the layout, but not new functionality), admin tools in the Tools area (Beheerfunctues I believe in Dutch), and the Snippets which provide functions that can be called by other addons.
Sure, several ideas in the Hints module would be nice to have in general, e.g. the fine grained access rights on a "per section basis", but the core package can not pick up each and every idea that appears to be useful in some usage scenario. One of the advantages of WB is that it is not too complex and quite easy to use even for beginners with close to zero background knowledge about content management systems.
We have discussed several aspects before I have decided to write the Hints module. The implementation as a content addon that is only visible in the backend, with a built-in permission management was the most straight forward path to go. Maybe, if future WB versions are more flexible, e.g. when there is an interface to register user-defined functions to the menu bar, or when it is possible to inject user-defined content at each place of the backend, things look different, but for now the only solution would be a fork of the backend theme (to insert a new item in the menu) in combination with an own infrastructure to hold the information which hint shall be shown where (there are no page ids or section ids for the whole backend. They onty exist in the page tree).
