I can't figure out a way to do this, but does anybody know how, or if it's even possible, to put your scheduler on the main display as a wallpaper? I'm not very good with remembering dates, and the alarm notices only begin an hour before a scheduled event. My old phone was nice because you could customize when to receive a notice, whether it be a day, a week, 2 weeks, etc. in advance.
