Horrible on mac

This app has so much potential. I rely on it for work, yet it never seems to work for me as it should. I depend on my mac for gestures. I love swiping between full screen pages because that’s what a mac can do! That’s what a mac supports! You never need to compromise on screen real estate for any of your apps. And Slack for me needs to be full screen, so I can follow long threads at work, so I can see large images, so I lose none of it! When I open a document while in fullscreen, and then attempt to exit the document and return to my conversation or channel, it always manages to turn black. I am unable to close the application, minimize it, nothing. I have to force quit the app every time. Please please please fix this.

Yo! can you not write your application in electron?

I get it, electron is magical for whomever is programming. It’s a total ball of dirty lard for anyone who uses a laptop. My battery life goes from 10+ hours on a full charge, to under 4 when I open slack. For now I’ve resorted to just using slack in the browser, but it would be nice to have it as its own system app, as long as it doesn’t pound my battery life a sailor in port after being on the sea for 6 months.

Have never hated an app more in my life.

It never works, is confusing and will lock you out of your account randomly. I have spent more time trying to find my workspace, then I have used it. Save yourself the headache and don’t start with this app.
