Agreed. I wrote a blog post outlining a way to get around this. (https://medium.com/building-things-people-want/slack-is-too-...) The gist: turn off all notifications then flip them back on by channel. Still doesn't address de-coupling of pop-ups and sound, though.
Thanks! We actually started with NLP libraries, but fell back on plain old regex, which in the end was the right tool for the job, though it got a bit hairy. (Nice to hear from someone who can appreciate it.) As for daylight savings, we use the browser to get a current GMT offset on your first request and determine an Olson TZ, which we cookie. Subsequent requests are passed off to a Node instance for processing along with the time zone, which also processes posts from Slack and HipChat. And yes, MomentJS and Moment Timezone are the workhorses here.
Took a trip back to 2002 and visited the Account Settings / Personal Information screen to change my password. No alerts or redirects on login to change credentials. (But evidently an exciting "deal frenzy" is important enough to highlight in all caps and red text in the nav bar). Ok, so the PayPal DB wasn't affected, but does that matter? PayPal account is fully linked up there.
