Sure, the plug-in is far from perfect. There's some code in compose.c
that tries to guess some useful default values for the layers it
preselects. This code could certainly be improved. I am not sure
though if it makes sense to attempt to guess the compose mode from the
given layer names. It's probably more useful to remember the last used
mode (which is what the plug-in does already).

As I said, IIRC there's already some code that attempts to select the
layers called hue, value, saturation if you select HSV mode. It
doesn't seem to work very well though. We would happily accept a patch
that improves this.
