I finally got
fancy-preview working, and I found the place (around line 97) in the script to add to the list of environments which it catches (to add propositions and so on). But what I can't find after a quick read-through is a way to have
fancy-preview pick up
\cref, and other
\ref-like commands. Does anybody know how to do this? (I don't know perl or low-level latex, so I could have easily missed something obvious.)
I much prefer using
\ref. After spending way too much time setting up
fancy-preview, it would be pretty disappointing to have to give up
\autoref to use it.
EDIT: After looking into this a bit further, I don't think this is controlled in the
fancy-preview script. I think it's in the actual
fancytooltips.dtx, around line 756. I don't yet know how to adjust this code to also redefine
\autoref, but I think I'm at least looking in the right place.
