multiple interaction with actor

  • do you need the pieces to movement simultaneously:

Here you can see that several can open / close at the same time, each tracking its own movement progress individually. Or one at a time is enough?

  • the middle drawer is open

What happens when I click the bottom one? Should the middle one close first?

  • can a drawer remain half open?
  • can the opening / closing be interrupted?

Trying to establish how feature-rich this needs to be before I suggest something.
