I've been using the anime thread for Dragon Ball Super to discuss the differences between the anime and the manga of which there are quite a few. But I decided to make a thread here to start doing that.
I'll repost a few of my posts from the anime thread on the subject:
And now, Chapter 24
---
This chapter has a fairly significant difference. It mentions how all attendants of a Supreme Kai have healing abilities, and it's revealed that Trunks was made the Supreme Kai's attendant just before he fought Dabura in the future. So he had healing abilities that he wasn't even aware of until the Supreme Kai offhandedly mentioned it.
Zamasu also has cool portal abilities he didn't have in the anime.
