That's a good point. I just looked in the settings, and you can set it to limit by time on website, instead of time in a particular app.

I may experiment with that, if there's not another option. The issue is that you have to come up with a huge (constantly updated) list of distracting websites. And I know how my monkey brain works - it'll work hard to find the distractions. ;-)

BTW I recommend ActionDash highly. Free, and seems to work exactly how I want (except for this annoying thing about the PWA apps).
