Having the UserIDs of Players in the output log would simplify the process of getting the UserID of a Player when reading the output log.

Currently VRCX uses the display name that is written into the output log and attempts to look up the user using the user search endpoint. This leads to VRCX making a lot of search requests especially in very active lobbies.

If the output log would contain the UserID along with the display name VRCX could avoid making these unnecessary requests along with making it easier for users to file moderation reports while also assisting the moderation team in investigating malicious activity.

In addition to that the user search sometimes does not return the user when searching the full display name, so it would also aid in providing UserIDs to those where they would normally be missing.
