In the 9 months I have been with GENI with a Pro membership there are a couple of very helpful features that have been dropped. That has been a disappointment. I would definitely be willing to pay a "Deluxe Pro" monthly fee to have them restored. Those two features are the following:
(1) Full Tree Export
Until MyHeritage took over GENI, I was able to export my entire ancestry. Now that is limited to only a fraction of my ancestry. The reason this is important to me is because it allows me to do certain kinds of significant genealogical research which is simply impossible with GENI in any practical sense. For example, when I import data into one genealogy program on my computer, it allows me to see each and every line of descent from one ancestor to me. Sometimes that shows dozens of lines. GENI has no feature like that which shows every line. I would be glad to pay more to have this export function restored and available to me.
(2) Ancestors Total
Up until the past few weeks the home page Statistics listed how many ancestors I had. (Now it's capped off at 5,000 and has become a meaningless figure for me.) Having the total number of ancestors listed was a major encouragement to me as I started out and saw that number growing. It certainly motivated me to plug away at the research. And as it continued to grow I would share with my friends on FaceBook how many ancestors were now in the list. This was great advertising for GENI, and my friends were astounded that anyone might have that many. As a result, a good number of my friends have asked about GENI and its costs and its other features. Just before GENI capped this statistic at 5,000 I had reached almost 11 times that number (just over 54,000). I suppose that GENI has eliminated this feature because it takes up more computing power and slows down other GENI server functions.
Regardless, I'd be willing to pay more to have a "Deluxe Pro" membership with such features restored. (And maybe you could give such members those private note fields in each profile where they could store their own private notes and research information.)
