The user can directly choose whether to mirror via Y0 plane or the current active plane.
- Workflow problematic, as
- when entering the command, the user should have decided for the right plane already as the preview is immediately shown
- if the plane is not the right one, user can choose several options from related context menu, to change the plane, but even using another, the preview is not updated, but should (workaround: switch off and back on preview icon to get the expected update)
