v1.2.0

PDF page navigation: PDF preview now supports Previous / Next page buttons to browse all pages in the document.
On-demand PDF rendering: Pages are rendered one at a time when navigated to, with local caching for visited pages. This significantly improves loading speed and memory usage.
Fixed PDF top clipping: PDF content now aligns from the top and scrolls correctly, no longer cut off by the header area.

【1.1.2】
• Preview TIFF and PDF attachments; multi-page PDFs supported.
• Preview window is centered for a cleaner layout.
• New Options page: you can hide the in-message preview button and use only the toolbar button for a cleaner UI; default stays the same.

【1.1.2】
• 支援 TIFF、PDF 附件預覽，多頁 PDF 也 OK。
• 預覽視窗置中，版面更順。
• 選項頁上線：可關掉郵件內的預覽按鈕，只留工具列，介面更乾淨；預設不變，隨你開關。

Image Preview v1.0.2 Release Notes

This is a stable release that addresses previous feedback and improves image preview reliability. Thanks for user input!

Key Changes:
- Fixed messageId retrieval mechanism to ensure reliable loading of attachment lists (no longer falling back to DOM scanning).
- Improved filename display: Correctly decodes MIME-encoded filenames, supporting Chinese characters, spaces, and special symbols (no more generic "Inline image" names).
- Optimized image loading: JPG/PNG attachments now preview correctly, fetching dataURL from background script to bypass permission limits.
- TIFF/TIF support: Displays a placeholder and note for TIFF files, as they are not natively supported in web previews (users can download to view).

Bug Fixes:
- Resolved issues with attachment loading errors in content script by moving API calls to background.
- Enhanced logging for better debugging during development.
