Were you able to get any backtraces of that with e.g. Valgrind or native OSX
tools?

I added OSX comments to the manual performance section and restructured
it a bit.

My assumption is that it's due to reading from graphics memory where
SDL/OSX had mapped the Hatari window.  Because of how the ST graphics
modes are implemented (only updated parts of screen are converted),
the code needs to read the area of the screen left below the square on
*each* frame.  Falcon gfx code updates always whole screen so it shouldn't
have this issue, at least as badly.

At least you/somebody would need to come up with a design of what the UI
should look like with all of these options you're interested about.

These layout suggestions can be done as ASCII because Hatari SDL UI widget
positioning is character based.  No Hatari coding (knowledge) is needed for
that, you just need to remember to keep the dialog sizes small enough
(< 64x25) that they actually fit to the Hatari window.

After there's some consensus on how to fit all the options to the UI / what
the UI should look like with these extra options, it makes sense to start
implementing them.
