Here is the link for my CombatReticle beta version including different reticle color settings for weapon pair main and backup:
CombatReticle beta weapon pair colors
Please test it a lot and tell me if everything works, or not. Tell me how to rebuild any bugs in detail please so I can fix them. If we got a version which is stable and performant I'll release it as a patch.
I also changed the internal stuff so there is a global table CombatReticle now, and some other errors like global variables named "ctrl" or "settings" were removed/renamed as well to fix compatibility issues with other addons.
Libraries were removed as well so please be sure to load LibStub and LibAddonMenu-2.0 as standalone libraries!
