A facility is provided for controlling application features. In various embodiments, the facility assembles an indication of features, starts a controlled application, and provides the assembled indication of features to the controlled application so that the controlled application can disable a feature of the controlled application. The facility can include a controlling application that is adapted for assembling a set of tokens that identify features by adding or removing tokens when a user of the controlling application selects a command associated with the controlling application, and a controlled application that, when invoked by the controlling application and provided the assembled set of tokens, controls a feature of the controlled application based on the assembled set of tokens.
