I don't know why the slack desktop client is so popular. It's almost no different from the web client, but eats more RAM if you already have Chrome open. Just pin Slack in a tab and save your memory
In-dock notifications and system notifications are my reasons, as well as a dedicated window I can alt-tab to instead of tabbing through browser windows, then navigating to the Slack tab.
(I realize that for some people, "hiding" Slack in a pinned tab may be a feature.)
I know, it's a minor kvetch. But it's a minor kvetch I can solve with a gig of RAM.
If you are happy, no problem. I'm posting for general info.
It does. In fact, it keeps displaying an annoying blue-colored topbar telling you that your life will be better if you enable notifications (fortunately, with the option to snooze it or dismiss it completely on given machine).
Emacs-slack can get you all of that:-)
