Plugin possibilities?

Hello

I’ve started playing around with the Plugin editor. It’s been very challenging and I wish it was just as easy as the app editor. I’d like to know if the following things are possible within the plugin editor.

  1. Can you create a group element, and can you give it a data type?
  2. Can you create a repeating group?
  3. Can you combine elements? So that for example, an element can be inside of a repeating group?
  4. Can you create an input form that the end user (not the bubble developer) can type into?

Thank you
