A truly great extension! We installed this on all of our 200 Chromebooks across the 3 special schools i work in and it has greatly helped our students use technology to learn. It not only helps our dyslexic learners, but also our autistic and ADHD students by helping remove distractions and making the web a more accessible place. Support is fast and efficient, and updates are very regular with new features constantly being added!
