I think the core problem is still tab clutter. Every time I hop onto my iPad to do some light browsing, I have less anxiety. I don't keep many tabs open on mobile/tablet, but I'm already counting 8 opened here as I'm typing on my laptop. Sure, almost everything mentioned in the article is problematic. Then again, maybe it's just us programmed to hit Ctrl-T too much over a decade...
The closed tabs are saved in a searchable list so if something actually important gets closed you can find it again, but I find that 99% of the time I don't even notice that it has auto-closed hundreds of tabs I've opened over the course of the day.
I think I used to tell myself that leaving tabs open was sort of a 'soft bookmark', but now I just bookmark stuff that I genuinely want to come back to, and let the rest of the unimportant stuff I stumble across just disappear.
