Regarding this paragraph:

"If you have at least one node in the scene, you can create guides by dragging from the horizontal or vertical ruler towards the viewport. A purple guide will appear, showing its position, and will remain there when you release the mouse. You can create both horizontal and vertical guides simultaneously by dragging from the gray square at the rulers' intersection. Guides can be repositioned by dragging them back to their respective rulers, and they can be removed by dragging them all the way back to the ruler."

In Godot 4.3, repositioning a vertical or horizontal guide requires the user to actually grab the guide at the ruler's edge (that is, in the spot where the guide is emitted from the ruler), instead of trying to grab it in the middle of the viewport (the intuitive way). Trying to do so results in nothing, unless there is a hidden configuration somewhere that could change this behavior.

I believe this should be clarified in the above paragraph to avoid confusion.

What is the best practice for position of reusable components, i.e. scenes?
When dropping them somewhere in a parent scene, we want them to appear around their origin, where the gizmos show.
This would imply we should keep the roots of these components at 0,0.
However, the scene preview shows 0,0 in the top left corner, making it impossible to preview the components, unless they are moved to the center of the screen (i.e. screen_width/2, scren_height/2).

However, the scene preview shows 0,0 in the top left corner, making it impossible to preview the components, unless they are moved to the center of the screen (i.e. screen_width/2, scren_height/2).

You can add an autoloaded scene with a Camera2D node positioned to Vector2(width / 2.0, height / 2.0) to your project, so that scenes anchored to (0, 0) can be previewed when run directly. In 4.4 and later, you can also use the Game tab's 2D camera manipulation (on Windows/Linux X11; game window embedding requires 4.5.dev for macOS).
