--this way the model items can become aware
of all data changes and become visual
responsive accordingly. All changed data
should use the italic paradigm... If a
value is changed from its original value
can become italic in order for the user

from Layouts model that is currently found in settings
window and that way the settings window will be
simplified and is going to be responsible only for
the UI elements of the window and NOT the QTableView
internals
