v0.2.0

What's New

Frontend Modularization

• Split monolithic 2400-line app.js into 17 ES modules, bundled with esbuild
• Cleaner architecture for future feature development

Multi-Instance Launching

• Run multiple Minecraft instances simultaneously
• Per-instance session tracking with independent SSE connections
• Resource warning dialog when combined memory allocation exceeds system RAM
• LIVE tag on all running instances in the sidebar

Install Queue

• Installing multiple versions no longer silently drops the second request
• Sequential queue with per-instance sidebar progress bars
• Detail panel shows "INSTALLING..." or "QUEUED" states correctly

Game Output Improvements

• Timestamps on every log line
• Per-instance tags (auto-shown when multiple instances are running)
• Instance filter dropdown to isolate one instance's output
• Vertically resizable log panel (drag the handle, height persists)

CDS Auto-Repair

• Changed -Xshare:on to -Xshare:auto — corrupted archives no longer crash the game
• Automatic detection of CDS errors in game output + archive invalidation
• Concurrent CDS generation guard for multi-instance safety

Settings & Theme

• JVM performance preset now persists correctly (was silently discarded)
• Theme saved to backend config — survives localStorage wipes
• Settings save shows a toast and stays on the page instead of navigating away
• WebView2 Destroy() called before exit to flush localStorage

UI Polish

• In-app styled dialogs replace native alert()/confirm()/prompt()
• Instance name uniqueness validation (frontend + backend)
• JVM preset indicator in instance metadata (with ZGC Java 17+ note)
• Distinct colors for selected vs running sidebar items
• Stop button bottom-aligned with session timer
• Log panel max-height prevents collision with settings buttons at low resolutions
• Dev tools adapted to instance-based architecture
