Feature Summary

Add support for persistent bookmarks that allow users to mark important lines or sections in a file and revisit them across sessions.

Motivation

While temporary navigation marks are useful during a single session, users often need to keep track of key locations in their files over time—such as TODOs, reference points, or frequently edited sections. Persistent bookmarks improve long-term navigation and productivity, especially in large or modular projects.

Proposed Design

• Allow users to add a bookmark to any line via shortcut, gutter or context menu.
• Bookmarks can include optional labels.
• Display bookmarks in gutter and a popup.
• Bookmarks are saved in a project file for projects and in editor data based on file path.

Acceptance Criteria

• Users can add, edit, and remove bookmarks.
• Bookmarks persist across sessions (and are stored per project in project mode).
• Users can navigate to bookmarks via UI or keyboard shortcuts.
• Bookmarks are displayed with labels and line numbers in a sub-window.
• Bookmarks do not interfere with file content or version control.

• Allow export/import of bookmarks for portability.
• Separate in project bookmarks from file based bookmarks and keep project bookmarks in project file.
