Improvements

• Products Mega Menu: New dropdown menu in the header showcasing all Playcode products: AI Website Builder, language playgrounds, and developer tools.

New

• Three Agent Modes - Choose how the AI works: Ask (answers questions without changing code), Plan (creates a plan before coding), and Agent (full autonomous coding). Switch modes anytime from the chat toolbar.
• Plan Mode - AI asks clarifying questions with a step-by-step wizard, then creates a detailed implementation plan in plan.md. Review and edit the plan before executing.
• Execute Plan Button - After reviewing the plan, click Execute to start implementation. The AI reads your (potentially edited) plan and follows the steps exactly.
• Multi-Select Questions - When AI asks questions, some allow multiple selections (like choosing features). Single-select questions auto-advance to the next question.

Improvements

• Smarter Task Tracking - AI now merges task updates by default instead of replacing the entire list. No more accidentally losing your task progress.

New

• Delete Files - Ask the AI to remove files from your project. Full undo support to restore deleted files instantly.
• Move & Rename Files - Ask the AI to move files to different folders or rename them. Undo restores the original location.

Fixes

• Undo Button Fix - Clicking undo on a specific change now correctly reverts that change. Previously, the last change wasn't being undone.

New

• Real-time Preview Updates - Watch your website update live as the AI writes code. No more waiting for the entire file. See changes appear progressively in the preview as they're being written.

Improvements

• Tasks Shown Inline - AI task lists now appear inline with other tool messages. Click to expand and see progress like "Tasks: 2/3 done, 1 in progress".
• Visual Task Status - Tasks now show clear status icons: checkmark for completed, spinner for in-progress, and circle for pending.

Improvements

• Click to Open Files - When AI reads a file, click the tool message to open that file in the editor with the exact lines highlighted.
• Accurate Line Range - Read tool now shows the precise line range (e.g., "Read index.html:1-78") so you know exactly what the AI saw.
• Clickable File Lists - In "List files" results, click any file path to open it directly in the editor.
• Cleaner Visual Hierarchy - Read and list operations now use muted text styling to keep focus on the code changes.

Improvements

• New Default Model - Grok Code Fast 1 is now the default AI model. It's fast, affordable, and produces quality code, best value for most users.
• Cost Tier Indicators - Each model now shows a cost badge ($, $$, $$$, $$$$) so you can easily see relative pricing without complex math.
• Better Model Descriptions - Every model now has a clear, user-friendly description explaining what it's good at and why you'd choose it.
• Reorganized Model List - Models are now sorted by cost tier (cheapest first), making it easier to find budget-friendly options.

Fixes

• Angular Hot Reload - Fixed critical issue where Angular projects would crash after 2-3 code edits with "Maximum call stack size exceeded" or "JIT compiler not available" errors. The fix: upgraded to Angular 21 with zoneless mode. No more zone.js, cleaner hot reload, smaller bundles, and better performance.

Improvements

• Angular 21.0.2 - Updated from Angular 17 to the latest Angular 21 with modern features and improved performance.
• Zoneless Change Detection - Angular template now uses provideZonelessChangeDetection() for cleaner architecture without zone.js overhead.
