Feature Request: Find/Replace & Document Outline Tools

Problem

Efficient navigation and text management tools are essential for productive editing in complex LaTeX documents. Currently, Modern-LaTeX-Editor lacks advanced find/replace capabilities and a visual outline (table of contents, section navigator, or headings sidebar).

Proposed Features

• Find/Replace: Support for basic search, regex mode, and bulk replacing of text. Live highlighting of matches within the editor.
• Document Outline/TOC Sidebar:
  • Visual sidebar listing \section, \subsection, \chapter, etc., for quick navigation.
  • Collapsible sections for large documents.
  • Option to jump to definitions for \label and references for \ref/\cite.
  • Sync between editor and outline (highlighting current section in view).

Benefits

• Faster editing, review, and navigation of long LaTeX projects.
• Easier management of document structure.
• Improves user experience in both academic and technical authoring.

Acceptance Criteria

• Find/replace function with regex and replace all.
• Working, interactive sidebar or outline tool for document navigation.
• Jump-to-label/ref feature both from sidebar and context menu.
