I would not like to think it is useless (but I might be biased, since I wrote
that macro generating routine).
That lengthy macro is what you need to do by hand to end up with a binary
image selection outside the plugin. Currently there are no global values
stored anywhere for the selected colour space and its parameters (what you set
with the plugin). Those are local to the plugin instance while it is running
and applied to only to the current image. I am afraid that you will need to
use that macro and modify it if you want to create a macro that just sets the
values.
So while setting the sliders and not thresholding was not the purpose of that
plugin, once the macro creates a binary image (which is what a thresholding
process should do), you could transfer the corresponding selections of the
ROIs to the original colour image, do a Create Selection on the binary image
and then Restore Selection in the original (so you will need to keep a
duplicate of the original open before the macro is run).
If instead you want to create an image where the binary white is the original
in colour, then you can use the AND operation between the original and the RGB
version of the binarised result.
