Hmm, it seems that \subfs functionality is built in through the same mechanism. Will study this some more...
yes, but there in successive calls the last one counts
\addff{x} \addff{y} \addff{z} -> z is used on top of the current font's set
\feature{x} \feature{y} \feature{y} -> all are used on top
we might end up with replacing \addff etc by one mechanisms
\feature{+someset} : add \feature{-someset} : subtract \feature{=someset} : replace
I like this proposal for its use of only a single command with the add/remove/reset in the args. If \feature ends up being too generic, maybe \fontfeature or \fontfeatureset instead? To keep things more in-line with current ConTeXt syntax, you could do something like the following: \feature{add=foo} \feature{subtract=bar} (or sub, remove, etc.) \feature{reset,add=baz} Which would also allow, e.g., \feature{add=bar,remove=baz} similar to how we're used to using key:value pairs in so many arguments, and being able to combine them in one function call.
