I'm here on behalf of my 70-something sister, who I'm trying to wean away from Adobe Creative Suite because she's on low fixed income and cannot afford Adobe's highway robbery. She bought Affinity Designer and Affinity Photo, but she is having trouble with her visual acuity diminishing and cannot see the tools. The grey-on-grey scheme may be pretty, but it's not terribly functional for those of us who are getting older. She is very depressed because she depends on her graphic design work to help keep her focus off her painful fibromyalgia, and it's her one great joy in life to be able to do design. She already has a big honking monitor, but the Affinity tools stay too small even when she's at full screen for her to be able to see well enough to work.
Is it possible you could add a hover-over-tools feature that folks can enable to be able to see the tools better? I know you've got the tool tips, but they are really too small for people with older eyes (and I am one of them) to be able to read without straining. Or maybe a skin that people can apply who need help in this department?
