It simply works (even on El Capitan beta)
Flawless app, I can’t find any issues with it. Eats just a little bit of memory with a nice badge icon in the dock with unread messages counter, notifications works fine, as well as hotkeys. You can stretch out the menu bar icon just a bit in the next upgrade and this one will get even closer to a perfect app (-;
