### What should this feature add?

There are two associated features requests here.

1. Add the ability to toggle the visibility of all wires, and/or individual wires.

e.g. V key
.
.
2. Add a node (or set of nodes) that transfer outputs to inputs; without wired connections.

I've created a mock-up of a possible implementation below.

psychedelicious on Discord has suggested:

"...you could have Portal In and Portal Out nodes. Each Portal In node gets an ID or name. You can put anything into a Portal In node. Each Portal Out node has a dropdown for the available Portal In nodes, and can be connected to another input field.

Or, a Portal node that you connect your VAE to. Then, other VAE fields in all nodes could have a button that lets you link them to existing Portal nodes."
.
.
The reason for this request, is that it can be difficult to discern where a node's output is being sent in complex setups.

### Alternatives

I am not aware of any portal-like node in InvokeAI atm (as described).

Nor am I aware of any way to hide wires.

### Additional Content

In the node mock-up above, the Channel setting will accept numerals (e.g. 1, 2, 3, ...).

While the Node and Type settings would be automatically set; based on the channel or input connection.

e.g.
One connects a Noise node's Value output to Portal Out; this sets the Output Node setting to Nosie, and the Output type to Value.

For the Portal In node; setting the Channel to 1, will set the Input Node setting to Noise, and the Input Type to Value.
