One thing first: I don't think your working style is yet covered by the
code.

What is included is decided by the `tab-line-tabs-function': "By
default, use function `tab-line-tabs-window-buffers' that returns a list
of buffers associated with the selected window."  You may have a look at
and try the alternative values.

AIAIK, none supports manual reordering.  Tabs are always sorted by some
algorithm, so manual reordering doesn't make sense.

I think it would be best to make a feature request (M-x
report-emacs-bug) and CC Juri Linkov <juri@linkov.net>.  That already
worked very well for me in one case.  I've CC'ed him in this answer.

What you want should not be hard to achieve.  But I wonder if it would
be desirable to have all the time: an Emacs session can have hundreds of
buffers, lots of them internal and helper buffers or irrelevant for the
user.  You definitely want some kind of filtering and maybe also some
way of automatic sorting I think.
