Here is my suggestion: Let the user add their own toolbar buttons to quickly access features within Orion. These could be added from the "Customize toolbar..."-interface. For example: You export to PDF a lot? Add a toolbar button. You use Low Power mode a lot? Toolbar button. Have a favorite tool in the "Develop" menu that you use constantly? Toolbar button.
My suggestion for GUI: In the customize toolbar pane, have two tabs (think old macOS System Preferences). One tab is standard toolbar buttons, the other tab is "All" or "Advanced". There you can have miller columns to dig down the menus to drag your preferred feature to the toolbar.
This should ideally be a standard feature from the macOS system, but it shouldn't hurt for Orion to be a trailblazer.
Thank you!
