Fixed PDF exports that produced a blank page after recent ChatGPT changes.

The export preview now returns correctly after saving or cancelling printing and can be printed again. A failed diagram no longer blocks the entire export: its source and error are included while other diagrams and messages remain available.

Also reduced false conversation-change errors during history loading. Includes improved Circuitikz detection and accented mathematical labels. No new runtime permissions or dependencies.

Improve automatic rendering of electrical circuits in ordinary TikZ picture blocks.
Fix accented text labels inside math formulas while preserving upright text, subscript sizes and the original editable source.
Includes the previous fix for readable text in PDF exports captured from dark mode.

Fixes PDF exports captured from ChatGPT dark mode: headings, paragraphs and mathematical text now use readable ink on white paper. Diagram colors and deliberately colored text are preserved.

Includes the updated ChatGPT integration, message selection, navigation recovery and focused diagram zoom. Reload ChatGPT and capture the PDF again to apply the fix to an existing preview.

Restores inline diagrams and export controls for the updated ChatGPT interface. Improves cached conversation navigation, loading states and editor controls. Adds focused mouse-wheel zoom and an Ask ChatGPT to fix action that preserves the draft and never sends automatically. Updates message selection and PDF export preview.

Known issue: PDF text captured from ChatGPT dark mode can be too light on white paper; a follow-up fix is being prepared.

New in 1.5.0

• Export rich PDFs with rendered equations, tables, code, images and complete vector diagrams. The extension scrolls the conversation to load earlier messages and captures them as they appear.
• Select individual messages or any combination for PDF, Markdown and plain text. Choose the conversation, answers only or prompts only, with search and selection controls. The complete JSON archive remains unfiltered.
• Save one assistant reply with its optional preceding prompt. Review the selected content in the export window before Save PDF opens the browser print dialog.
• Preserve diagram proportions and embedded fonts regardless of preview zoom or pan, including successfully rendered local edits.

PDF uses the displayed page rather than reconstructing it from the conversation API. Scrolling can trigger ChatGPT’s normal loading requests. Hidden tool details and collapsed content are not expanded automatically, and attachment files are not downloaded.

Improved compatibility with diagram fragments generated by ChatGPT. Common math, unit, chemistry and plotting dependencies are detected automatically, while explicit options and custom macros are preserved. Fixed brace decorations, cancellation strokes, Fraktur glyphs, Unicode labels and comments in quantity arguments. Added bundled scientific packages, clearer compilation errors and real-engine regression tests.
