I have hard times always remembering i did deactivate and managing daily usage. We should be abble to run a calendar and have a weekly schedule ''pre-built'' and override option. So i could plan school day-off next monday so i can change sunday and monday once, instead of having to go back twice and causing tantrum to kids. I guess it would be easy to add and it would make a huge difference (honestly, i'll look for other solutions if it's not available next year).
Also, generic toughts, it's not easy to get own to make new posts...
