Ok, but the entire top row is now 90% buttons, tabs, and address-bar. Leaving me to struggle with the trackpad to position the mouse on a tiny sliver of border. Is there a keyboard modifier for move-mode?

There is, but it's disabled by default. Use

    defaults write -g NSWindowShouldDragOnGesture -bool true

Then restart, and now while holding Ctrl-⌘ you can click and drag _anywhere_ on the window to move it.

WHOA that is amazing! That would solve so many of this issues.

Seems like it should be enabled by default, unless it already has another binding.
