If it is a check-box, tab or toggle button would have to be
considered. I am under the impression that the latter is more common,
but I don't know the rationale behind.

Very good idea. It could even work both ways, and use that for
saving/loading parameter "presets".

The GUI would be auto-generated, so adding parameters means no extra
programming effort. Not putting things on the GUI would, thus, be a UI
design decision, to keep it from being cluttered.
Wow. This is getting more and more ambitious. Will have to see what
