I'm KD. I grew up using Adobe and I stopped using it in 2013. I have too many hobbies and too many professional licenses to renew on biannual time frames...
What I'd like to see:
e-book versions of your textbooks (I carry my GoPro, my drawing tablets, and my laptop... I don't need to lug around 3 books too)
Animation timelines in Affinity Designer. (Not that important, I can just use Clip Studio Paint EX)
If Affinity suite ever goes to a cloud subscription model, then I will drop it pretty quick. A rather steeply priced lifetime pass would be attractive.
Buying software makes me feel good. I still prefer it without subscription models, and I don't want it to feel like I need to buy a new version every 6 months. (See: Call of Duty or iPhones)
Right now, Affinity's payment model is fine how it is-- but consider offering a lifetime pass for a lump sum.
I dropped Adobe, Ableton Live, and most subscription software because of the cloud subscriptions--- Yeah, I pay for Netflix and streaming services, but do I really have a choice?
I already have subscriptions in my profession--Don't want any more. Solution? Lifetime passes.
