sorting by Link-to-table field
It would be nice to be able to sort records in a view according to the Foreign-key-value of a Link-to-table field. At the moment, that field-type is not present in the list of fields to sort on.
For clarity: it is clear that the sorting now would only be applied to the key-value, and not to any linked fields in that linked table, but that is fine. Being able to sort on the key, could be enough in some cases. Being able to sort on linked fields (and / or displaying those linked field) is a separate desideratum.
