There is any plan in the future to add filter for every object's
field? Which is the reason for this limitation
I am not sure what the original reason was, but I do know object
views (and layouts, for that matter) aren't being evolved, so don't
expect to get new behaviors added there. Instead look at using the
collection provider or manual/dynamic collections with your object.
Even if the filtering of collections has the same limitation (I am not
sure how that works), you should get more traction with a feature
request on collections than on object views.
Also it's possible to return a file as a result of a custom
object action?
I recommend opening a new thread for this new question. It's not very
discoverable buries in a comment here.
