Stick to a theme
I like things dark. And it's great that you have a dark theme. That is, unless I click on the Calendar or Notes icon on the right. Then my eyes get BLASTED with a big white screen. That's just rude. Why can't you guys be consistent across apps? And to be honest, it would be better if the icons opened the Notes and Calendar in that same window, like the "Starred" and "Contacts" screens do. It's like you have completely different teams working on projects and not talking to each other at all! It makes for a decidedly unpleasant user experience.
