> The max I have got is around 200 tabs and even that was a considerable stress on my brain.
Here's the trick I think:
I and many others use tabs to offload the brain. For those who have read "Getting Things Done" I think this is similar.
We don't think about them, just look them up if and when we need them.
Kind of the same way as a journal or notebook: it doesn't stress me that I have hundreds of pages I might never get back to; it eases my mind that if I need to get back it is still there.
I use Tree Style Tabs and a couple of extensions on top of that so sometimes I'll copy a subtree as a nested markdown list and store it in Joplin, then close it.
But no: 600 tabs like I've had more than once was totally feasible years ago and should be no match for a moderns system.
That said as long as people don't try to force me to change the way I work they are free to do it their way.
