Quality features I enjoy paying for. * Buy once model. Trial + buy is best. Some YouTube videos of people using the software is often good enough. If you offer a free ad supported version, and a buy once to remove ads version I will almost always buy the no ads version. * Local saves. If you want to sync with the cloud that's fine, but I want to do read/writes from my local device whenever possible. * Local computation. I have fast chips, I don't mind using them. * Privacy. Do your competitors track me but you don't? Let me know. * Modifiable appearance. I really put value in being able to change fonts and colors. I think this is a bit niche.
