Features Syntax Highlighting - Clean, readable color scheme with each row type clearly distinguished. GROUP, HEADING, UNIT, TYPE, and DATA rows each have distinct colors. Works with dark and light themes.

Outline View - See all groups in the file at a glance in the Explorer sidebar. Quickly navigate to any group with a single click.
Code Folding - Collapse and expand individual groups. Great for navigating large AGS files with many groups.
Table View - Open AGS data in an aligned, editable table with Ctrl+Shift+T. Color-coded rows matching the editor, group selector dropdown with descriptions, inline cell editing with arrow key navigation, and real-time two-way sync with the source file.
File Summary - Generate a comprehensive markdown summary with overview statistics, group counts, location summaries, and a records-by-location matrix.
