Indicate out of data repos in Sync Replication view
In the absence of a "Sync All View" in Sync Replication View, have a visual marker to indicate out of data repos so it can be determined at a glance which repos are out of sync and require syncing. Probably a different colour for repos with incoming changes and a different colour for outgoing changes, and something to indicate there are both incoming and outgoing.

Do you know you can have more than one repo in the same sync view?? This is how most people use it, so you can calculate all syncs in one shot and you won't need the icon you are looking for.
