As a developer you can design with more empathy, here are a few tips that are not expensive and I and other people with disabilities or even healthy persons would appreciate: -allow the usage of the application without the mouse(if it is a painting app then maybe skip this), so don't break the navigation with Tab key, allow selecting buttons and activating them with the keyboard, if you have a search input allow me to press Enter to start and not to hit a search button with the mouse, try to allow the users customizing the key bindings(depends if your app needs key bindings) -don't use horrible colors for fonts, like light gray on white background, even if it feels readable on your screen other screens differ so better use some more contrast -if you make a mobile or desktop application use the user defined colors and font sizes, test your app with the larger font sizes and see how it looks.
