I would go even further in the opposite direction. I think it's so important to get RM8 out the door that it should be shipped with fewer than planned new features if that would get it out the door faster. Of course it shouldn't be shipped until it's been well tested and it shouldn't be shipped with no new features. But from a user's perspective, essentially all RM progress is at a standstill until RM8 ships.
I admire your faith Jerry but sadly don't share it. Fifteen years ago I would have been completely onboard but so many simple gaps since the release of RM4 never having been closed or fulfilled my faith is damaged and I have become very skeptical of development goals and deliverables.
Your logic would be perfect for a development strategy especially for Mac users but would require a long term commitment from Rootsmagic to iron out the bugs, complete the planned feature list and not get lazy and be tempted to hold back some planned features for RM9 if such a version ever becomes a reality.
All just my opinion.
