Version 4.1.23

New & Improved
• Upgraded Popup Menu Experience: Add, sort, and delete favorites for more efficient management of frequently used tools.
• Enhanced Custom Highlight Colors: Custom color menus, group boards, and shortcuts now display both colors and their numeric codes, making filtering and operations faster and consistent across devices.
• Improved Study Set Style Import/Export: Batch-select components during import/export for a clearer and safer workflow.
• Upgraded Manual Sync: To prevent data loss from overwriting local changes or conflicts, manual sync now supports a pre-sync backup option. Choose between “Backup & Sync” or “Sync Directly” for better data protection.

Fixes
• Fixed an issue where custom highlight colors did not immediately refresh in tools or menus.
• Fixed an issue where favorite menus were not properly imported with study set styles.
• Fixed an issue where spaces between words in Baidu Translate queries appeared as plus signs, reducing translation accuracy.
• Fixed overlapping buttons in the table of contents at narrow widths and corrected the “+” symbol to English text.
• Fixed an issue preventing YouTube videos from displaying due to “robot verification” and improved Bilibili video playback for better multi-platform compatibility.
• Fixed an issue where Pro users were not immediately notified when selecting brushes beyond their access level; added clearer prompts.
• Fixed a crash caused by dragging blank space into the page comment area.
• Fixed app freezes triggered by paste operations.
• Fixed crashes that could occur when importing study set style templates on lower system versions.

Other
• Continued improvements to overall stability and user experience.
