As I expalined above the better and easier solution would be just to add "Filter" to the menu, which allows filtering for language, ...In the MP1 version we have a grouping already implemented. There are 3 possibilities: Disable grouping, manually define groups of sites or auto group by language.
This adds another "hierarchy" on top of sites - I can add this to the MP2 version of OV as well.
Only problem back when I did MP2 OV was figuring out how to tell MP2 that the starting workflow state is either "sites" or "groups" depending on a configuration setting. There are user whoe do not use many site and wanted to have no groups as it adds an additional navigation step every time you enter OV.
Can you agree with that and add update the plugin?
