Create only once Indicators Settings in Effects page
Try to follow the new Dock/Panel settings approach (the configuration window is created only once when first called and it is the same window used for ALL panels/docks) for Indicators settings also.
Currently each time the user changes indicator style or cycles between panels/docks with different indicator styles, for each change the indicator settings are recreated.
A better approach could be the PrimaryConfigView to provide a model of Indicator pages that could be consumed afterwards from Effects page. Something like Tasks pages are already doing. If that succeeds the memory consumption will be reduced more and the some nice animations will be provided also for indicator settings pages when the user switches between different indicators.
