Hope this message finds you well. 1] Display color - please add light theme colors as an option in settings to have a clear vision. [I wear glasses/spectacles and have a little difficulty reading the screen, not used to reading the screen for a long time] 2] Font size - please add a feature to increase /decrease for a better user experience. 3] PYQ - This is probably a tough task, topic-wise PYQ + vedio explanation, number of questions asked since 5 / 10 / 15 years, difficulty level. Even if a link is provided from the best source will save time. I understand your busy schedule, so no worries if you can't get to these add-ons right away. I'd really appreciate it if you could look into them whenever time permits. THANK YOU
