Have you noticed Slack slow down/use too many resources as a result of being an Electron app? Honest question, I've never used Slack, but have used other Electron apps and never really have any issues.
The Slack app on my mac kept using up a lot of RAM frequently. I'd have it running for a few days and suddenly the laptop would be unusable, with only ~200MB of RAM free. Slack would suddenly be using 2-3GB of memory. Kill slack and everything works fine.
I've restored to using slack on Safari now. This problem still occurs, but reloading the slack tab is easier then finding and killing the slack process.
I'm on a new computer and Slack takes at least a second to react to mouseclicks. It's completely ridiculous since, let's be honest here, Slack is a pretty basic chat app.
We moved away from slack due to it crashing peoples desktops (Mac, Windows and Linux all have had this problem). I've not used other electron apps though, so maybe I'll stop blaming the underlying tech :)
