Now that LrC has the Content Aware Erase ability, and the Object Mask ability, please add a button in the Object Mask panel to erase the content within the mask using content aware erase. Similar to PS. The mask created would very likely be better than the selection made thru the current Content Aware Erase tool.
Object mask Defined, Overlay displayed, would be great to clcik on a button to Content Aware Erase at this point
