I would like to organize the content for my team by themes, creating pages and subpages within the WorkApp. The menu would show a theme (Project List, i.e.) with subpages for each project. Another theme could be "Purchase Requests", with subpages showing the purchase orders I've issued, and so on. In this way, there would be a tree menu, organizing the content by themes.
I really miss a way to hierarchically organize the menu in WorkApps, with topics and subtopics. When there are many options, navigation is confusing for the user.
