I think I understand your frustration but one thing is for sure, the ability to easily create WordPress themes from simple HTML files introduced with Pinegrow 2 in april 2015 is a totally innovative and unrivalled feature and represents a major business asset for Pinegrow.
This does not mean in any way that it will take precedence over the other expected features, whether minor or major, but just that it contributes significantly to the sustainability of Pinegrow, all versions combined.
