Thanks.  Some comments/questions:

> +@cindex internal tab bar

Why "internal"? copy/pasta?

You use the term "minibuffer window", which I think is sub-optimal:
that window is also used for displaying the echo-area.  I prefer the
term "mini-window" instead.

This is a mouthful (is it really important to say this here?).  Please
rephrase, in particular with fewer instances of the passive tense.
(The next sentence after that is also unnecessarily passive and hard
to read.)

I made a few minor editing changes in the text you installed.

Thanks for taking care of the manual.
