Show HN: Shrugs.app, a Native macOS Slack Client

Amazing. Still boggles my mind that these huge companies can't invest in native development. You never really understand how constrained Slack is once you see what multi-window setups could look like. The current UI is mess and this is a great solution.

When I try to sign in, there is a threatening banner "This app hasn’t been reviewed or approved by Slack. Learn more." But nothing happens when I click on "Learn more". I decided to quit then. :(
