HTML Architect: Pin/favorite items in tree for focused workflow

Problem
When the tree grows large, working with a few specific items becomes painful — you constantly scroll up and down, expand/collapse branches, and lose context.

Proposal
Let users mark any tree item with a star or pin icon. Pinned items could include their sub-items.

A separate tab — e.g. “Favorites” or “Pinned” — would display only these items, preserving their hierarchy. The user can then work exclusively with this filtered subset.

Benefits

  • No more scrolling through the full tree for frequently accessed items
  • Easier focus on the items currently being worked on
  • Personal per-user view without affecting the actual tree structure

Open questions / nice-to-haves

  • Should pins be per-user or shareable?
  • Persistence across sessions (probably yes)
  • Possibly multiple named “pin groups” instead of a single favorites list?
