Thanks for this PR. I would add the filters in the place place as the management screen for consistency and re-usability. Here is where these filter should go. This way, we can "may be in other PR" add sort and other filters if needed.

@xtomas have you seen Mike's comment?

[xtomas]

@Piedone yes I have already seen Mike's comment. I actually work on it in my git repository. On a copied Lists code just to be sure it will be available for my project even if my PR will not yet be finished and 3.x version not released. If it will work well, I will update this PR with functional and tested solution.

I also had and idea to enable filtering content picker field in contained types only (for example two content types in a list part and one picking from other, let's say Partner with list of branches and discounts where discount can multiple pick from partner's branches). It was easy to implement but I actually do not need it anymore due to business requirements change. And it is not easy to describe in UI.

OK, thanks, let us know in a comment here once you've updated the PR.

The contained-type only feature is not something that would be generally too useful, I think, but I'm not sure I fully understand what it's about.
