• Language Switching – Automatically discovers localization folders; switch languages on the fly
• Detail Preview – Click any card or relic to see a large preview with full stats and flavor text
• Editor Gutter Icon – When opening a card .cs file, a gutter icon appears for quick preview
• Auto-Detection – Detects STS2 mod projects via Sts2PathDiscovery.props or Steam installation
