I'm a longtime fan of Affinity Designer as an affordable Illustrator-killer for figures, and... it's now free?! www.canva.com/newsroom/new...
Highly recommended if you're sick of paying Adobe $. Maybe Canva can buy NPG too and get rid of the OA fees.

Why we made Affinity free, and how we’ll keep it that way
We’ve made Affinity completely free, empowering professional designers with studio-grade creative software, supported by Canva’s sustainable ecosystem.

Wow. "NIH" canceled my co-mentored (with Dave Sulzer) PhD student's F31 funding. His work is on understanding the genetics and neuroscience of language learning disorders. F31 provides no indirect $ to Columbia, just pays his salary. Not that it should matter, but he's an American citizen. W.T.F.
