v2.1.5

(07/11/2025)

• Feature updates in v2.1.5:
  • Added table alignment dropdown consolidating column alignment controls.
  • Introduced wrap-around toggle for Find/Replace navigation.
  • Improved toolbar dropdown styling with dark-mode support.
• Fixes:
  • Improved dark-mode preview readability for text and highlighted matches.
• Maintenance:
  • Bumped application version to v2.1.5.

Full Changelog: v2.1.4...v2.1.5

v2.1.4

(03.11.2025)

• UI consistency improvements across the app:
  • Standardized toolbar buttons to a consistent icon + text pattern.
  • Unified popup title bars with blue headers, close buttons, rounded corners, and consistent shadows.
• Redesigned Find/Replace as a centered dialog with header, improved spacing, and dark-mode support.
• Replaced image cap prompt with a proper Image Cap dialog (validation, persistence, Enter-to-confirm).
• Dark-mode scrollbars across browsers (added color-scheme hints and custom scrollbar styling).
• Bumped application version to v2.1.4.

v2.1.3

(29/10/2025)

Features and improvements in v2.1.3:

• Implemented heading rendering inside blockquotes so Markdown headings within ">" blocks render as proper HTML headings.
• Added "image from link" auto-resize option (dialog checkbox). When enabled, the editor measures the linked image client-side and inserts responsive markup with a configurable maximum width (default: 800px). Runtime cap can be adjusted via the toolbar control; preferences are persisted to localStorage (keys: md-auto-resize-images, md-auto-resize-max). Toolbar control id: #btn-image-cap.
• Word wrap (beta) improvements and details:
  Works in both the editor and the preview. Long words and URLs wrap at safe boundaries to avoid horizontal scrolling.
  Code blocks use white-space: pre-wrap while preserving indentation; inline code wraps without breaking layout.
  Blockquotes, lists, and table cells are hardened to wrap content cleanly without overflow.
  Toggle via toolbar button (#btn-wordwrap) or keyboard shortcut (Ctrl+Alt+W / Ctrl+Shift+W).
  Preference persists in localStorage under md-word-wrap.
  Credits: feature made by LoserFan2020 with contributions from Phuc and Hung.
• Misc: reordered blockquote/header parsing so headings inside blockquotes render correctly, fixed related JavaScript and CSS syntax issues encountered during development, and applied small UX polish to dialogs and controls.
