Configurable hidden class attributes

[anselmdk]

I think it would be beneficial if certain class attributes could be hidden from a table. See Member here, if we could hide all the hash items etc. that would make the model easier to read.

I think that should be configurable in the query string just like you can do with tables now (&exclude=SiteTree,Page). The format could be something like &excludeAttributes=Member[TempIDHash,TempIDExpired].
