I had the idea of creating a command that would "link" two windows

not a unique ID for each window, So I came up with the proof of
concept unique number patch below.
But first a few question:
Is this something that is implemented and I just missed the code?
Is this the correct way to implement a unique window ID?
Would the VIM community be open to accepting a patch if I brought
this code up to standards?
Can you tell us why you think you need unique window IDs? This seems
like something that could be done with a mixture of buffer-local,
window-local, and/or tab-local variables or options.
1. bufnr() is unique, but winnr() and tabpagenr() are not.. I feel
that this is confusing and unexpected from the point of view of
someone creating a vim script.
2. The real problem for me is that find_win_by_winnr(4,null) returns
the fourth window in the current page. I can't find and work with a
specific window.
At the very least, you should certainly not REPLACE the existing
window number. The window number is set in a predictable way and can
be used to switch to specific windows with <C-W><C-W>. Making the
window number unique and static would make this impossible without
first calling a function to figure out what the window number is.
This patch should create the function uwinnr(), leaving winnr() alone.
As Ben said ...
You can "tag" a window by creating a window-local variable and you can
"tag" a tab page by creating a tab-page-local variable. Both combined
result in "unique" window ID.
To find the window with this ID again, you have to go through all
windows in all tab pages (is this what you are worried about?) -- but
this is only the worst case, when the layout has changed. Of course you
will check the last remembered tabpagenr+winnr first, then all windows
in the last remembered tab page, and after that all windows in all tab
pages. It's something that a vimscript can do.
