There is at least one reason to use the magnifying glass : with the
SyncWindows plugin from Joachim Walter, using the tool magnifies all the
synchronized windows, whereas using "+" or "-" magnifies only the active
window (the one that is actually clicked). Wether it is an inconsistency of
the plugin or a feature is questionnable, though.
