Our editors are used to opening a (MM) component from within another component. Sadly in the new Experience Space you can only add or remove. Could this be again part of the options? Maybe it was skipped because you can then not open the item in the same window, but we would also like to choose ourselves to open in same or new tab (before all opened in new, now all open in same, but both is handy in different situations/moments of content creation).
