Whenever I open Character Viewer, I want the Favorites category selected by default as shown in the image. Instead, I find that even if I selected Favorites in the last session, next time the category selected by default is the first category below the horizontal dividing line below Favorites in the left side bar (the Greek category in the attached image).
Is there a way to make Favorites selected by default? If this is not possible, I want at least the category selected in the last session remains selected in the next session. In fact, that is the behavior for all the categories below the dividing line, but not for the categories above the dividing line. For example, in the attached image, if I close Character Viewer while the Arrows category is selected, next time the same category remains selected, but not for the Frequently Used and Favorites categories.
