Hello,
My menus are designed as follows.
In the header is the company logo on the left and at the right edge is the date and the username.
The menu allows you to change the theme. If I now choose the Rhino theme, the date and the username is left at the logo. If I configure the menu with the new features, the representation of the Rhino theme (date and user right) works fine, but if I now choose an SC8 Theme, the date and Username are no longer displayed.
For me this means that the SC8 and SC9 themes are not compatible with the new features. This means that SC9 provides just 1 Theme (Rhino).
