While we already have the ability to target relative clauses by user with filters, I think it would be quite useful to allow us to target these in the GI results grid configuration as well.
An example use case would be would use the row or field styles to color code based on ownership. Something like this:
=SWITCH([SOOrder.OwnerID] = @Me, 'green20', [SOOrder.OwnerID] <> @Me, 'default')
Our GIs end up having a lot of tabs on them and many times we'll have a version of a tab for everything matching a particular filter set with a second version setup to target the current user. Sure there are ways to cut down on this but I know my users would appreciate a way to know which records are their responsibility at a glance.
