Seems to me Painter has reached its zenith. Or more accurately, it reached its zenith several years ago and is now simply trying to keep up. I suspect the code has become impenetrable in some areas, who knows, but it's clear that for whatever reason it's attained its functional peak.
The last three releases have contained nothing more than minor tweaks and the occasional performance improvement. That's fine by me, I'll continue using 2018 because it suits my needs and it's still the best all round traditional media emulation package. However, it would have been nice to have at least a nod towards supporting those who earn their living with Painter but hey ho, after 18 years and so many detailed suggestions and input I couldn't begin to quantify it, all of which has been ignored, I have no expectations in this area.
