Improved card relationship dialog
The attribute "card relationship" should be improved in two ways:
A) The popup where the linked card can be selected needs a full text search field. It's impossible to scan through hundreds of cards manually.
B) It should be possible to create a new card on the fly and add it as a relationship. Use case: Let's assume you have a model for "Customer Meeting" and you want to create resulting tasks that are linked to this meeting. Then you need to be able to create and link new cards on the fly.
