Must admit that I am not seeing much difference but I have not been doing much family history work recently after being completely put off by the 'improvements' to Ancestry and FMP last year and earlier this year.
I hate starting by putting in a name with a few details then trying to filter down to what I want to see. Most of the time I just want to go directly to a particular source like one year's census.
I also hate the pop ups for place names with county and country. I much prefer being able to enter a town then use that as a keyword to find different occurrences - one record might have it in one way and another in a completely different way.
I hate sliders. I much prefer putting a year in one box and the +/- figure in another box. And perhaps name or place with a wildcard rather than again a slider.
From a brief look, the only thing that I can say is that it is not as bad as the 'improved' FMP.
