Here's a thought...

Perhaps you could put on the official wish list the ability to read the
ambient light with a Spyder and use that to set the PreciseLight
settings (or something similar) in PrintFIX PRO.

Good idea? Bad idea?

I can see (particularly as they share the PreciseLight (TM) name), where this idea would come up. But the PreciseLight color temp slider in PrintFIX PRO and PLUS has to do with the particular illuminant metamerism of a given printer, ink, and paper combo. There is no way that the Spyder could know about that...

Also, I find it a lot handier to have a few sheets of quadrant prints at different PreciseLight brightness and color temp settings to hold up against the wall in a gallery or other display location, then to lug a laptop there, and try to hold a Spyder up in the same place. And the client will be a lot more comfortable choosing one quadrant print for degree of shadow detail, and another for neutrality, then trying to do something on a laptop. I often just ship the quadrant prints out, without going myself... which wouldn't work well with a computer, special software, and a Spyder.

The Spyder would miss the particular combination of viewing ilumination angle, and viewer angle as well... as it just reads globally. The eye is the thing...

I had no clue the slider adjusted for metamerism.  Is there a standard
measurement for that?  It would be nice to characterize inks and
determine the degree of metamerism they each have.

This is visual, not measurement based stuff. The degree of compensation will vary with both the lightsource, and the ink/paper combination. And some users may choose to add color adjustments in addition to the single dimensional color temp adjustment, in more extreme cases. My solution is to avoid more extreme combinations... now that fairly well mannered inks and black generation options are available, using poorly mannered ones in work for sale, and especially in B&W work, can be avoided.
