Feature Request: Ability to Show/Hide Sketch Nodes

Description:
Currently, all sketch nodes are always visible in the editor, which can lead to visual clutter, especially in complex sketches. It would be beneficial to have a feature that allows users to toggle the visibility of sketch nodes.

Proposed Solution:

• Add a UI control (e.g., a button or checkbox) to show or hide all sketch nodes in the current sketch.
• Optionally, allow toggling visibility for individual nodes or groups of nodes.
• Remember the visibility state per sketch or globally, as appropriate.

Benefits:

• Reduces visual clutter in complex sketches.
• Makes it easier to focus on specific parts of a sketch.
• Improves overall user experience and workflow efficiency.
