This PR implements visibility management for the file menu icon and adds QuickTools visibility control per tab.

File Menu Icon (Pencil Icon)

• Hides the file menu icon from header when active editor tab type is "page", otherwise show it

QuickTools

• Adds hideQuickTools boolean property to EditorFile (defaults to false)
• Allows per-tab control of QuickTools visibility

Usage

new EditorFile("My Tab", {
  hideQuickTools: true
});
