Regarding fixing the salvo and single selection dials its one or the other with ARB.If you make the dials look better in the scope views then it looks bad in the F5 attack map view and vice versa.I never use attack map so I rather have a working salvo selection dial in the scope views and will use the mod I posted though this comes stock with ARB GUI.
Also,ARB was based on Ahnenerbe GUI and that mod itself doesn't have a working single selector switch at the uzo,attack and observation so that will never work until its fixed.
