First off, thank you! So glad I found Joplin. For me it is the perfect replacement for Evernote!
My only feature request, please, is to add the ability to sort reminder notes by reminder date.
I put all my reminders into one notebook. When I look at that list of notes, I can't see what's next up. Nor can I see if I've accidentally overlooked a reminder. My workaround is to occasionally scroll through every reminder to check the reminder date so I can see if I've missed any.
Apologies if there's already a way to do this, that I haven't found.
