[Feature Request]: Add visual indicators for inputs without wires, when the wires are hidden.

[JorgeR81]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

Now that there is a button to hide the wires ( #1063 ), people will do this more often.

So it may be worth adding a visual indicator when an input has no wires.

Proposed workflow

When wires are hidden, the input dots with connections could have a different shape.

I didn't think much about the shape. This is just an example:

An alternative would be showing the different shape on the inputs without wires ( e.g. a circle )
You could reuse this shape ( that is now replaced ).

I think this would probably look better than the example above.

By the way, we can still make connections with the hidden wires.

Is this an intended behavior of a bug?

This is one of the reasons why I suggested the visual indicators.
Because we can unplug wires accidentally, while they are hidden.

If you want to allow this, you could also show the hidden wire while it's being dragged. 
Now we only see a black dot.
