its the same for any application. apps are always developed with a
particular look and feel. unless they are build to look native
wherever they run.
yes setup should ideally be just a single copy. from installation of
the entire system to application updates. although im very biased
towards a document centric paradigm where this issue is simply
nonexistent.
