Unfortunately, your points aren't numbered, but I'm confused by a couple of them. - Finder has had tabs for a few releases, and I can't recall the last time I had multiple Finder windows open at the same time. I use tabs for everything. - By "sliding cell" do you mean the columns view? I use the list view roughly 100% of the time, so I'm no help there. - On my system, quicklook opens a preview to the left of the finder window, so it doesn't cover the finder window. I think I must have moved it over there in the past, and it remembers. - My system shows me every single dotfile, hidden file, and everything. I don't recall which setting I used for that, but zero things are hidden. - Do you not have right-click, Services, New Terminal Tab at Folder? If not, then that must be something I installed in ages past. Finder isn't perfect, by any means. It conflicts with how I like to do things semi-regularly. But I think a few of the issues you've raised might be solvable. At least that would lessen your pain a little. Some of the differences between the defaults and what I see on my system might be down to this: https://github.com/mathiasbynens/dotfiles/blob/master/.macos https://github.com/mathiasbynens/dotfiles/blob/master/.macos
