*snip*you are confused about my message here. I want an indicator that can be identified 10 feet away without trouble. If you can do that now, great for you. I have grandpa eyes, I have trouble comparing the current block square and 99 percent black square that tells me that day has an event. Yes, MS should ignore people with grandpa eye, I understand your argument. But, that's so discriminating users who doesn't have a good eye sight as you.
Phones are not designed to be viewed from 10 feet away so complaining the UI doesn't work at that distance is unrealistic. From 10 feet away I cannot see ANY detail on any app on my phone.
