This suggestion / request is about as simple as it gets:
I love the app, but in terms of how many unique symbols we can assign to separate contacts, your selection is very, very limited, surprisingly.

Pleeeeaaaase, give us at least another 15-20 choices for symbols. Past those 20 symbols, a great idea would be to just add simply the option to assign an uppercase letter as a notification symbol. That's an extra 26 right there. The symbols are ultimately way more important to me, but it'd be great to have even more options.

Thanks so much for your time and your efforts with the app! I recommend it to all my friends!
