VisualShader: Add ability to close "Create Shader Node" window by clicking on anywhere on screen

[Foyezes]

Describe the project you are working on

Working with visual shader

Describe the problem or limitation you are having in your project

Sometimes if I accidentally press right click and open the "Create Shader Node" window, I have to drag my mouse to the minimize button.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

If there was a system to close the window by clicking on the spaces outside the window that would be super helpful.

Also being able to open a node's setting by directly right clicking on the node directly, instead of having to select the node first will be good. Currently if I rick click on a node directly it opens the "Create shader node" window.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

If this enhancement will not be used often, can it be worked around with a few lines of script?

This will be used often

Is there a reason why this should be core and not an add-on in the asset library?

VisualShader is core

I'll add that it is very standard UX that this kind of Add Node UI does not have the commitment of a full modal dialog. Compare Godot to its peers. In all these videos, when the UI to add a node is open, I am left-clicking to try to close it. The actions taken to open the dialogs vary per program.

Only Godot requires clicking a button on the UI popup to close it. It is also very jarring that right-clicking on an empty graph in Godot is such a high commitment action.

I can see the desire to have a way to add nodes to the visual shader editor that is a full window with a close button; it's a similar logic to having a complex Create New Node window in Godot's 3D editor. However, if we have that, it should be a separate action from the Create New Node UI that appears when you right-click on an empty graph. The UI that appears when adding a node in an empty graph, or adding a node from dragging a connection, should be low-commitment and allow left clicking anywhere to escape it.
