Years into transforming the workplace, Slack continues to be as essential to teams as ever. Chatting with your colleagues in dedicated channels is at the core of this productivity powerhouse, but don’t snooze on its direct messaging tools, app integrations, and world-famous emoji support. If you need to gather the team for that one final push, you’ll want to do it in Slack.

Does not work well with iPadOS 16

When resizing the window of Slack, the changes to editing a post are lost.
When pressing ENTER on the iPad keyboard, the message is not sent; you have to press a button. But this button is hidden behind a tiny floating language selection & dictation bar. I had to move it out of the way, and quickly hit ‘submit’ before the bar jumped back, a matter of milliseconds. I know Slack used to be a game company, but this is not the type of game I’m interested in playing :)
I also find the app to respond slow on iPadOS, as if it’s not native but some kind of ‘HTML shell’ that doesn’t really bring the best of the native CPU/GPU capabilities.
Lastly, I think they need to rework ‘search’. I would like to see a more clear distinction between ‘search everywhere’ and ‘search within the current channel or private conversation’. It takes ages to find something now. I also would like to see a more user friendly search query system (AND/OR) where I can add criteria. Right now it doesn’t ‘feel’ right - I know that doesn’t really help but perhaps they’d benefit from a larger user-acceptance phase for UX.
Luckily it’s miles better than Discord, which although more powerful, is not easy to use or grasp.

One Step Forward, Two Steps Back for iPad

The recent iPad App update misses the mark quite considerably. In some ways, it is almost as if Slack doesn’t understand its users. No longer easy to see all unread messages in one place - which was a feature I regularly requested for the desktop app. Now, the iPad app has been turned to be quite bland. Seems like the “Dark Mode” folks won the design argument; as the new app no longer supports the desktop or web app color themes; which now makes the iPad app incredibly difficult to know at a glance which team you’re viewing. Also frustrating are the 3 or so “Unread Direct Messages” you can see, when you tap “Show All” it takes you to the “Direct Messages” sidebar that sorts in its own way, with unreads strewn about. Also, Direct message addresses are much harder to read; too much text all clumped together. Unfortunate for the iPad app, Slack has taken a once very useful version (preferred as a second screen in some cases over the desktop app) and made it into a giant iPhone app. The iPhone app now also suffers from this Direct Message unread messages “Show All” problem. The only way to return some of the missing sort and see all DMs on the iPad app is to select the sort option of “by recent” but it does not group unreads. 7 years using Slack, and this is by far the most disappointing iPad app “upgrade.” Repackage the desktop app for the iPad and call it “Slack Pro” for iPad Pro users who use their iPad in place of a laptop.
