I did a brief search and didn't find any user-suggested themes along these lines;
Evernote needs a more expansive reminder system. Repeating reminders, reminders by day of week, location, application launch, website launch, multiple reminders for one task/note, alarm settings and a calendar by which to set said reminders, or it needs to integrate with a system that already performs these services.
If it isn't ever on my mind, my notes are pretty much useless to me. I need something to keep me up to date. Right now I'm using GTasks for everything and it's note-taking system is dismal in comparison. I really love Evernote's system for note-taking, it's brilliant.
