As a Roblox developer and group owner, it is currently confusing and difficult to track user actions in groups because display names and usernames are used interchangeably in the audit log.
As you can see below, two users have the same display name, but different usernames. At first glance, there is good reason for confusion over who deleted what.
I am proposing that the audit log only display group members usernames so that group admins can easily and clearly identify which user is committing which action.
