"Quake mode first" mode of operation + improvements

[symphonic-navigator]

Hi, would like to use the Windows Terminal 100% in "quake" mode, but I'd love to see a few improvements.

Actually, if I could embed it into WPF already, I'd implement this myself, but I'm of no use when it comes to C++.

Here's what I'd love to see to make it 100% usable as "quake mode only":

1. Have tab indicators also in "quake" mode
2. Have it start "invisible" with Windows login, waiting for the hotkey
3. Mode for "auto width" based on number of splits (like "give 30% of screen width up to 100% per horizontal split") with start centered or off-centered
4. Never close - if last tab / split is closed, simply hide the window and when user hits the hotkey, start with 1 tab again

Optional:

5. Nice to have function: "shrink everything else on the desktop below the quake window", which would help me a lot when working out details in VSCode / Rider
