Two quick feature requests:
Have a "Remove Date" button or option for reminders - vs. removing the reminder all together, then retagging the note as a reminder
Add a "Today" button to the "Add Date to Reminder" menu option (right now, I just see "Tomorrow" and "In a week")
And here are the standard motivational phrases / thinly veiled threats to get your PMs to make this a priority (choose your favorite!):
I am a free user, and if I just had these features I'd totally become a premium member.
I'm currently a Premium member, but the lack of these simple features is astounding. If these aren't built I am totally leaving Evernote forever.
These features should be easy, based on my obvious visibility into your code and roadmap. I could churn it out in 5.4 nanoseconds myself.
I know your team works hard and has a lot of requests. You guys are doing a great job! And I hope you can get to my features. And I hope if I empathize with you, you'll feel a sudden obligation to keep me happy.
If you build these for me, I'll totally be your biggest fan ever and tell my friends/family/strangers about Evernote (note: adult version of "If you do this I'll be your best friend!").
I would totally pay more for these features if that shows you how valuable and a priority these features should be (so long as any pay increase is purely hypothetical).
I will try to be funny and appear like I'm not trying to motivate you / make thinly veiled threats, in the real hope that - er, never mind on this one.
