I've been a RootsMagic user ever since Wholly Genes folded, but I haven't encountered any "meaningless promises." I agree that "confirming this is on the enhancement request list" is annoying.
I would prefer that the list of enhancement requests were posted, together with the number of users who would favor each. Family Historian does that; it makes one feel more a participant in the software's direction than a supplicant, begging at the gate.
If I may say so, I think it's an error to lay one's frustrations on the heads of small specialized software companies. I know nothing of the economics of software publishing, but it's clear that if one wants to hire a full-time programmer at, say, $50,000 per annum, that one has to sell 1000 copies of a $50 software package every year just to pay the programmer alone -- and one hasn't even begun to pay for overhead, taxes, food for the family, a roof over one's head, and the services of a charming and technically adept person who has to write "confirming this is on the enhancement request list" on the forum, probably more often than she cares to.
