Never disrupt my work. Never switch tabs on me.
This happens all the time with Package Control messages. There doesn’t seem to be a setting to stop it. It’s fine if Sublime or PC opens a new tab, with some update info – just don’t take me there. Don’t hijack my screen and make me look at an update message while I’m working. Just open the tab silently like a browser would, and let me go there when I want to.
