Im not saying that people are selfish, im saying that the % of people who have Hi-Md, know about the software, can really use it for something, and actually KNOW HOW TO use it (it doesnt even have a GUI yet, massive blow for n00bz) is much smaller than you think.
Like many game developers say: Its done when its done.
Donating does not insure that the author will bring out newer versions, and not many people would like, or can, pay for an un-finished product.
BTW, if you are donating before you even have a HI-MD your doing twice the wrong.
what if you change your mind by the time you purchased HI-MD and have already donated?
