If I understand it correctly, Horizon has been retired as a product and is no longer under development or supported.
In this case, why are many core-features of the app still tied to a WeMod account? Additionally, many tools still require a WeMod pro plan. This results in having to pay, while in return recieving no support or developoment of any kind. Why not release a fully-offline version that the community can utilize now that WeMod no longer wants to support the app's features?
