Accidentally hit upon the FME Options under Tools menu in FME Data Inspector.
Background Maps can now be brought into FME Data Inspector while looking at your own datasets in the foreground.
There is also option to reproject to a specified coordinate system.
Awesome addition to FME :-)
Hat's off to the team that conceived and developed this.
It would be nice if other free web map services (wms, wfs) can be provided in addition to ArcGIS Online.
Would there be options to set transparency to user dataset anytime in the future?
