Thanks Robert, here is an example: the user logs in and views the contact tab. the user then clicks on the “Add New” which opens a New Screen. How do i know if a current or Main as a target will be a better option? how do i consider which to use?
For that specific use case, I would probably use overlay.
Personally, I find that I rarely use Main, and mostly use either of Current, Overlay or Slide In.
I’ll use Overlay for most form screens, and sometimes Current for larger, more complex forms.
I almost always use Current for Collection item Show Details.
But I think which you use mostly comes down to personal preference and the type of User Experience you want to provide. There is no hard and fast rule.
