Minor issues

The new UI sadly wastes a lot of space in the channel list due to big avatars and lots of padding - I wish there was an optional compact/condensed channel view similar to what the previous version looked like so I wouldn’t have to scroll so much. When you choose to “group by favorites” and also “group by type”, the favorites aren’t grouped by type. Apart from those issues, there have been a lot of improvements. Being able to pick an app icon and choose between themes is neat.

Developer Response ,

Thanks for the feedback harrybenson! The whole space you're seeing is because your server does not have the setting "Store Last Message" enabled. Please ask the administrator of your server the enabled here: Administration -> General -> Store Last Message. Then you'll start seeing the last message text filling the blank space. Thank you!

Best Open Source Slack Alternative

Rocket Chat is hands-down the best Open Source alternative to Slack. My tabletop gaming group needed the flexibility of hosting our own chat server, and after surviving the ruin of HipChat and exile from River, we decided we were done with hosted services, both “free” and “for pay” alike. Now we have total control over our server, the freedom to invite as many players as we like, and the knowledge that our creative content is safe.

The upgrade paths from early (pre-1.0) versions to 2.4 are strenuous, but well-documented. And there now exist turnkey server setups for hosting providers like Digital Ocean. Mobile is also well-supported, making Rocket the obvious choice for organizing all manner of volunteer and creative communities.

Pls minimize screen jumps down in iOS

In a large chat, live, this jumps entire screen involuntarily downward about every 3-10 seconds making following and participating a frustrating experience while online on wifi/cell signal. There needs to be a setting / mode to minimize to eliminate this screen instability please, when I am far ahead of the live comments being submitted far below where I am in the chat. Example, you have say a 15-30 line response to read from a colleague and you keep losing your spot—CONSTANTLY—as screen keeps jumping down like a bad robot. Good app otherwise. Thank you for working on this.
