How do I add non-string custom properties?

[mehran]

Hi,

I think it would be really useful if one could add a new property to a component (as it is done right now) and give it a non-string value. The user-story I have in mind is to set a plugins property to a grid and set it to [cellEditing] but since the designer converts everything into string, it doesn't work.

myArray: []
myObject: {abc: 123}

Then click add
