In some ideal future state, all of the Public profiles on Geni will be Master Profiles.
Currently HistoryLink provides a nice summary of the Geni Projects in the lineage (which includes aunts & uncles, too ... and that is a good thing).
It would be nice to have some kinds of summary of the portion of each generation (that exist on Geni) are also MP's; ideally, all of them would be (e.g. for all past any living generations). That way one could work on verifying the accuracy of the information of those currently-not a MP and then asking for them to be MP'd.
As I think about it ... maybe the "Master Profile" option could be a 3-state option: Off, show MP's, or show non-MP's. Although initially the non-MP details could be overwhelming; might need to limit the number of those shown (but not, of course, limit the counting of them).
A project-like summary table for each generation (e.g.: gen 4 MP's: 6/31 ... which would indicate 6 of the 31 found at that level are MP's ... the detail list would show which.)
