PUBLIC MARKS with tags interface & décision

When making design decisions regarding features in your application, it’s important to weigh the costs, not all of which are financial, against the potential benefits. Every time you add a feature to your application, the following things can happen: * Your application gets larger. * Your application gets slower. * Your application’s human interface becomes more complex. * You spend time developing new features rather than refining existing features. * Your application’s documentation and help become more extensive. * You run the risk of introducing changes that could adversely affect existing features. * You increase the time required to validate the behavior of your application.
