If you go to a lot of work making a phrasebook for a certain topic, you should be able to share it or get one from someone else. I like how there is an area in the app where there are phrases by topic, but why can't I make my own phrases by topic or get phrases from someone else by topic.

Think about language classes... I can share out to students or students can share out to each other! The adoption rate of the app could potentially go up if suddenly vocab lists by topic were a shareable thing!
