It would be nice to see changed FEATURES, just like changed USE flags compared to the installed version. Except in case of FEATURES, I don't really want to see them all, only when it changed, even if --verbose is passed (I always pass it to see all USE flags in --ask output, not just changed). My use case would be to see if the installed version was done with a FEATURES=-test (possibly temporary one-time cmdline case) during arch keywording work, as a way to easily see in my normal emerge -1va workflow that the previous merge was done without it, as to make sure it still isn't broken before wasting time on it (on a single core 800MHz).
