Membrane Software applications exist to provide you, the user, with features. Each feature represents one full segment of functionality, or in other words, one thing you can do.
A feature can be in one of these states:
An idea, not yet in development and perhaps not even fully formed
A work in progress, with active development efforts directed towards its completion
A work in progress that isn't currently in active development, but is planned for implementation later
An idea that has been abandoned and probably won't be revisited
A feature that has been implemented and can be accessed by use of Membrane Software applications
