Manipulate properties is now more convenient:

c.cfgimpl_get_settings().has_property('hidden') => 'hidden' in c.cfgimpl_get_settings()
c.cfgimpl_get_settings().has_property('hidden', option1) => 'frozen' in c.cfgimpl_get_settings()[opt]

c.cfgimpl_get_settings().get_properties(option1) => c.cfgimpl_get_settings()[option1]
c.cfgimpl_get_settings().get_properties(option1) => c.cfgimpl_get_settings()[option1]

c.cfgimpl_get_settings().add_property('hidden', option1) => c.cfgimpl_get_settings()[optiont1].append('hidden')
c.cfgimpl_get_settings().del_property('hidden', option1) => c.cfgimpl_get_settings()[optiont1].remove('hidden')

c.cfgimpl_get_settings().enable_property('hidden') => c.cfgimpl_get_settings().append('hidden')
c.cfgimpl_get_settings().disable_property('hidden') => c.cfgimpl_get_settings().remove('hidden')
