Hello,
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.
An example dialog for deleting nodes or ways:
>If you delete this element, one or more relations may become broken.
Relation membership can be managed in the Advanced tab. To learn more
about relations, see: http://wiki.openstreetmap.org/wiki/Relation
>
>Proceed?
>
>[ ] Don't show this again [Yes] [No]
And one for merging ways, shown only if necessary (not shown if all ways
are already members of the same relations, except relations with
type=restriction):
>If you merge these ways, one or more relations may become inconsistent.
Relation membership can be managed in the Advanced tab. To learn more
about relations, see: http://wiki.openstreetmap.org/wiki/Relation

>Proceed?
>
>[ ] Don't show this again [Yes] [No]||
