Some people in the thread said they preferred running Slack in a browser tab instead of the Electron app, perhaps to avoid the memory overhead of a separate browser instance.
The comment I replied to described a preference for the app because of OS navigation, e.g. Alt+Tab, a separate taskbar icon, etc.
This Chrome shortcut or Edge app trick lets you combine these approaches, running the website in your browser but giving the site its own main window that you can pin to the taskbar, set to auto-run, and navigate to like a native app.
I would have guessed the memory consumption would be similar given the sandboxed tab model of Chrome. Anyway... even if not, do any of you guys really find that the memory consumption of Slack is a problem for you in practice?
