FTB really is the best. I have tried them all, even Ancestry's FTM, which is use only for an off line backup. FTB just visually works better than anything out there. FTB has info right in the persons box when expanded, much more visually efficient than listing names in vertical bars, with info in another panel off to the right, and big KUDOS !! for putting in the To Do List Management on v 5.x. I was one of those who made the suggestion, and you made that feature way more powerful than I was imagining, and Green check mark icon, SO, SO useful. I don't have to dig through notes, rereading to see if I'm really done with a record.
Now, how about those extra purpose icons, like some way to place upt to may 4 custom icons, which could mark anything like military veteran, to color coded paths through the trees.
All my offline work for past 3 years as been with FTB. Great Job Development Team, management, buy them some beer :)
