Yes, same here.

Here it's at the bottom left.  I had missed it.  Thanks for pointing it
out.

Yes, and in plastik there's no button size like in others, but strangely
I managed to reduce the height of the title bar by reducing the font
size of the window title (to point size 8 bold).  Now the height of the
title bar is a lot closer to that of black square.

In this version, plastic doesn't have a button size option, but as I
said above, the height of the title bar is affected by the window title
font, up to a point.

That's what I've observed with plastik.

Blacksquare is still the winner for shortest height.

Thanks for this clarification.  I now see the cause of my confusion with
this.  In the display of all possible buttons I see text for "Menu" "On all
desktops" "Minimize" "Maximize" "Close" "Context help" "Shade" "Keep
below" and "Keep above" but only "Menu" and "Close" have the  associated
symbol: "X" for Close and ":>" (but with 3 dots in slight arc instead of
the 2 dots/colon).  There is no symbol for the others.  When I drag any
of the others to the fake title bar nothing shows up there but if I drag
the mouse over the blank fake title bar the cursor changes to the hand
with pointing finger, indicating that there is something to click or
drag.  Since I presume the fake title bar reflects the real one, I see
the hand cursor in 2 blank spots right next to the "X" (Close) which I
presume are the Maximize and Minimize buttons.  Any other buttons I drag
to the fake title bar don't show up but the mouse changes when I go over
the invisible button just dragged.  I can also drag it back out of the
fake title bar, so at some level the system knows the buttons are there
even though they're invisible.  If you actually see the symbols for all
the buttons, it's probably a bug that has been fixed in your version.

Maybe I'm missing some font package, but it should have given an error
if this is the case.

This makes sense, but I'm moving invisible buttons :-)

Thanks you answered the question earlier.  I leave my version of
everything for completeness.

You're right of course.

Lower left corner in this version.

Yes, I see ButtonWidth and ButtonHeight there.

Hopefully that won't be necessary now that I've learned a few more
tricks.  Thank you.

Very informative.  I too have learned quite a bit more.  Thanks again.

You have a wealth of information.  Thanks for sharing.
