A popular addon may work perfectly today and vanish tomorrow because its GitHub repository was DMCA-struck or its developer abandoned the project due to legal pressure.

Users must stay informed, manage multiple addons, and occasionally configure local installations (using "Community Addons" or manually installing via URL) to maintain access. These addons fall into two primary categories: and
