Loving it so far, here's a follow so I can wait for more updates :D
The only critique I have is the "sans-serif" option from font settings isn't technically sans-serif. It is also quite narrow to read as texts, which can be pretty eye-draining.
If you are looking for any sans-serif fonts (which only the dyslexic one is), think of either Arial, Futura, Lato, Roboto or even Century Gothic. Google fonts have a lot of free available options which I guess can be coded in.
