I know this can be considered a duplicate of tickets #3777 and #4879, but I'd like to elaborate on this issue.
Despite members of relations now being rendered a little differently, I still see some novice users breaking relations from time to time without noticing it. They use Potlatch because it is easy and because they feel they can skip a lot of technical reading. The visual language is a very nice feature when understood but it is evidently not that obvious to some users. A visual clue may indicate that something is different but it does not indicate what the difference is.
I suggest a warning that the user may disable through a check box (and re-enable in the Options dialog). The warning can briefly explain the possible consequences of operating on relation members and provide a link for further reading.
