Thank you everyone 
will we be able to change the order of items?
- Now the order is consistent (before it was kind of random) & everything you add will be added to the end of the list. So as a workaround, if you add the relations in the correct order, then you have the order you want. You can also delete one and add it again to put it at the end. Not the best but it’s something
- We are currently working on making them easily reorderable. So it’s coming
Does this mean we can set relations as required fields now?
No it’s not part of the feature
Is it possible to create new item? Somethink like tags?
Do you mean creating them on the fly? If yes then no, it’s not part of the feature
