Yes, this is what I'm suggesting. I don't know why I didn't think to exemplify it like that.

'Don't group pinned items' to me meant don't group pinned items together at all. Is 'Don't group pinned opened items together' clearer?

Yes this is what I meant. I hadn't thought to describe it this way. Thx for making it more clearer.

No. I thought I explained it. I don't know how to better explain it.without images. I just upgraded from Win7 to Win10 and the way I suggested is the way it works in Win7, what I'm used to. I'd just like that functionality back, unless it's not possible in Win10.
