Follow-up improvements to "Update subgroup creation page"
We're making it clearer to the users that they're creating a subgroup in the experience after they click on Create subgroup
button on a group page. The main improvements to the experience will be introduced through this issue: #354530 (closed)
This issue is for follow-up improvements. Consider:
- changing the copy on the left side of the screen
- add an explanation of what subgroups are and how they function
