Features

Android and Desktop are separate forks with separate option sets. Pick the client you run.

Mercurygram is two forks, not one app on two platforms: the Android client descends from Telegram for Android, the Desktop client from Telegram Desktop. They share the same goals and a good deal of behaviour, but each carries its own patches, so the options differ. Pick the one you run.

Android Every Mercurygram-specific option in the Android client: what it does, where it lives, and its default. Desktop Every Mercurygram-specific option in the Desktop client: what it does, where it lives, and its default.
