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.

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!

Scrolling is jumpy and buggy

Been using this app on iPad for several months. You would think a chat forum would be a pretty basic thing to get right. I guess it’s not. As you scroll through posts in this app, instead of a smooth view it frequently skips ahead or back. The effect being that as you are scanning the posts, whatever you were looking at suddenly jumps off the screen when something new either loads at the bottom of the scroll or something moves off at the top of the screen. It’s disorienting to say the least. Seems to be based on whether posts have images or not but I can’t be sure. It’s the app devs job to figure that out. I do know that the user experience is very annoying and frustrating. Makes it easy to lose your place and then you have to keep scrolling back and forth every few seconds to find what you were halfway through reading. Really disappointed with this app and do not recommend.

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.
