Speaking of first time user experience, there is probably a lot of room for improvement for the "onboarding" screen. It's kinda out of everybody's mind because you only see it once ever.

I get to see it more during development, and it doesn't look great.

The fact that we don't do any tracking or analytics complicates matters. It's really hard to tell whether a change actually has any positive effect. I literally don't have any data to tell me whether after we added the onboarding modal more new users stayed or not.
@Gargron tracking is uncool. Non-invasive feedback is cool
