There could be a better way which would be presenting them also by device model with cascading menus. Point is that it's not necessarily the case that the search is just through 5-12 profiles. It's likely through all of them and being parsed by some other factor that makes sense, like if the pop-up is for printing, that the profile class be prtr and not mntr.

It's just not interesting to me at all. I just want it to work. And I also think it needs to be system wide, not only user specific.

For the printer, they'll first be selecting mainly a proset (media
setting + profile) and it will be determined by their printer type and
media type. At that point they should get a usable print, whether they
come from sRGB and use the magic consumer workflow, or use profiled
printing. Of course afterwards they can reprofile, tune settings etc.

If they have installed a printer and are using a standard media, they
should be able to find the canned proset quickly from the install
dialogs.

Online they will locate special media types.
