Hi Rebecca, great program you wrote first of all, many thanks for that. The soft voice on the video was mentioned already, hard to hear unless one uses earphone. I also don't have the "ALL" on the chromosome selection, it's difficult this way to find a specific cousin by name (unless there is a way to do it).
I also would like to recommend a new function where you're suggesting possible matches for action, instead of us manually trying to find double entries from several testing companies (it's easy for those profiles we managed but many of our matches upload to several companies as well). That would be really helpful.
Will work myself more into GenomeMate but after importing 1500 matches from GedMatch (their max they show), over 1200 from 23andme and a couple hundred from FTDNA I will have my hands full going through the data and cleaning it up (merging, adding family tree info and other info I had so far in a huge Excel file).
Again, great software you wrote and putting it up for free is something that will help spread it to many genealogists!
