It would be great to be able to access the "object help" of a SAPUI5-Control from a dropdown-menu within the list in the library. so I could right-click a library entry (like Button) and select "Display object help" from there. So I would not need to add that element to my document first to get the button "Display object help".
Great suggestion Tim. Thanks for sharing ! :)
