This has important aspects:

• A ProWiki can be configured according to the needs of the specific WikiApplications or community. A ProWiki can look simple because it does not need to display all features available.
• The ProWiki system enforces flexible UserInterface configuration, because otherwise the Admin could not configure what the wiki to the needs of his community.
• This separation makes the development of new Commands independent from its actual use. They can be explored and used in those communities that are interested in them without burdening the userInterface of other communities.
