English

1. Editor and interaction

• Added Keypad Mode, with a compact layout designed for focused formula entry. Normal Mode and Keypad Mode now keep independent window-size memory.
• Added explicit alignment-point editing for multiline environments such as align / aligned; use & to choose the visual alignment position directly.
• Improved cases / piecewise-function editing, including multiline structure, alignment points, braces, and Enter behavior.
• Expanded the formula toolbar and command compatibility with more extended integral symbols, package commands, and matching rendering, copy, and export support.
• Unified default parameters, input behavior, toolbar state, and formatting behavior between the main app and Office editor windows.
• Improved custom formula hotkeys, Common tools, and Greek-letter quick input, with centralized persistent configuration.
• More workspace settings now persist across restarts, including layout, panel state, formula colors, font size, toolbar state, and editor mode.
• Improved compact-window and floating-layer layout to reduce clipping and overlap in menus, toolbars, and color panels.

2. Custom symbol system

• Added a complete Custom Symbol Designer for drawing and composing mathematical symbols on a canvas.
• Custom symbols can be registered as VisualTeX / LaTeX characters and used throughout the formula toolbar, autocomplete, MathLive rendering, and SVG / PNG export pipeline.
• Added symbol archives, runtime registration, glyph compilation, and isolation from built-in symbols.
• Improved visible-bounds cropping, toolbar sizing, sharpness, and baseline placement to avoid oversized, undersized, or offset results caused by full-canvas rendering.
• Improved drawing, scaling, rotation, layer management, reference glyphs, and eraser behavior.

3. Themes and interface customization

• Reworked the theme system from basic light/dark modes into multiple palettes with full theme-color customization.
• Main background, paper, elevated and recessed surfaces, selection states, accents, and formula-caret colors now share one theme system.
• Settings, onboarding, editor, formula toolbar, and Help Manual now follow the active theme consistently.
• Reduced unnecessary explanatory text in settings and editor windows to improve information density and usable space.

4. OCR

• Added Quick OCR with a streamlined screenshot, recognition, editor-return, and result-insertion workflow.
• Added Silent OCR, which can recognize a screenshot in the background and place the resulting LaTeX directly on the clipboard.
• Added an OCR status / HUD for recognition progress and completion feedback.
• Unified model selection, settings, and entry points for standard OCR, Quick OCR, and Silent OCR.
• Improved model switching, window transitions, screenshot triggering, and result delivery stability.

5. Office editor startup and performance

• Word / PowerPoint formula editors now use a more mature persistent / prewarmed lifecycle, reducing repeated cold-start delays.
• Fixed the main app stealing focus, incorrect window ordering, and icon issues when opening the Office editor.
• The editor can appear directly above Word / PowerPoint, with focus returning correctly to Office after editing.
• Further hardened true cold-start behavior.
• Added Office performance budgets and regression coverage to reduce the risk of formula-count-dependent performance regressions.

6. Word Ribbon and Office integration

• Reorganized the Word Ribbon and introduced a consistent VisualTeX icon set and command grouping.
• Main commands now cover inline/display picture formulas, inline/display OMML formulas, Edit Selection, Redraw Selection, Redraw Document, Picture / OMML conversion, cross-references, Update Numbering, numbering format, and document import.
• Office dialogs now more closely match the main app for formula toolbar behavior, parameters, fonts, font size, theme, and input behavior.
• Reduced repeated initialization during consecutive formula editing sessions.

7. Office add-in installation, update, and repair

• Added a more complete DOTM / PPAM version-detection system.
• Detects missing add-ins, outdated versions, incomplete files, and PowerPoint add-ins that have not been registered.
• Old DOTM / PPAM files can be overwritten directly by VisualTeX without manual removal.
• Office add-in status now distinguishes Install / Update / Repair.
• Updates can request Word / PowerPoint to quit and continue after Office exits normally.
• Update choices and related preferences are persisted.

8. Word redraw and document import

• Further improved Redraw Selection / Redraw Document for large formula sets and complex documents.
• Fixed paragraph layout, picture-formula position, and double-click edit targets changing after redraw.
• Expanded mixed-content import and regression coverage for prose, inline formulas, display formulas, and OMML.
• Uses stricter formula identity / metadata to preserve formula identity and original structure and reduce formula/text displacement after redraw.
• Improved target lookup and recovery in bulk operations instead of relying only on current positions.

9. Word equation numbering and cross-references

• Numbering settings are now persistent instead of session-only.
• Stabilized sequential, chapter-based, and section-based numbering, including . and - separator styles.
• Improved synchronization between Ribbon numbering controls and actual document state.
• Update Numbering now acts as a global repair command that can replay numbering in the formulas' physical document order.
• Improved numbering updates, sequential insertion, and editing performance for large documents; normal tail insertion prefers a local fast path instead of rescanning the full document.
• Improved ordering when picture and OMML formulas are mixed or formulas are inserted in the middle of a document.
• Repairs legacy numbering structures, orphaned SEQ fields, damaged helpers, and duplicate numbering states.
• Strengthened transactional rollback so failed numbering operations do not leave partial structures behind.
• Improved cross-reference / numbering coordination so middle insertion, reference insertion, subsequent editing, and numbering updates keep formula count, SEQ, and body REF fields consistent.

10. Help Manual

• Added an in-app Help Manual that opens directly inside VisualTeX without launching a browser.
• Covers the editor, hotkeys, Common tools, tiles, align, cases, matrices, Keypad Mode, OCR, custom symbols, Word, and PowerPoint workflows.
• The Help UI follows the active theme and uses improved typography and contrast for body text, navigation, headings, code blocks, and tables.

Windows addition

• PowerPoint format conversion: added conversion between picture, OLE, and OMML formulas so presentation formulas can be switched according to editability, compatibility, and output requirements.
