The show history feature of a single Mendix document is very useful in tracking the changes and analyzing the changes made with each revision (to a certain level). But when working with multiple branch lines, merges and again new branch lines, which depends on your development workflow, this history is not shown.
It would be nice to be able to view ALL changes made to a certain Mendix document, in all development lines. This provides a much better idea of how features are implemented, knowing the history of its function and support issues.
