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.

Hello Alex! We do appreciate your feedback. Thank you for choosing Rocket.Chat and for your support!

Messagaes aren’t displayed

The app is good for almost everything. The main problem is that it will “selectively” not display new messages. This has serious consequences when you type a response and see your response, and others have typed their responses and you don’t see them until you either force quit or some sort of refresh happens on the main page. It will also often place messages out of order if this behavior occurs within a room.

This is insanely frustrating to have to continually fiddle with the app (going out and back into rooms, force quitting, etc) to simply see chat room messages.
