Request: Caching channels on Discord app for offline-reading

I'm a long time train commuter, and when ever I see Discord app on macOS and disconnect from internet, the Discord app just trying to reconnect, dimming all channels. Thus I cannot read any messages in any channels until I reconnect😢.

Slack app is much better because it just notify the offline-status and I still read the cached channels, Discord app for macOS should adopt the feature.

Thank you,
