Hi all,
On our installation of phabricator which has neither legalpad nor harbormaster installed, when creating a herald rule both of these options show up: https://www.dropbox.com/s/p0z6r5eqj0awgwq/Screenshot%202015-04-27%2011.41.59.png?dl=0
Herald should not offer the option to require features from applications which are non-functional.
(I'm uncertain about what to do with rules set up prior to them being uninstalled)
