Recent Session Highlights

Progress Tracking Implementation (Enhancement #23)

Problem: No live progress updates during VM exports Solution: Implemented comprehensive callback system with channels and goroutines

Changes:

1. Added ProgressCallback field to ExportOptions
2. Created callbackProgressReporter wrapper type
3. Modified downloadFilesParallel to accept and use callbacks
4. Refactored TUI export flow to use goroutines
5. Implemented channel-based progress messaging

Cancellation Support

Problem: Ctrl+C and q didn’t work during exports Solution: Implemented context-based cancellation

Changes:

1. Added cancelExport field to tuiModel
2. Created exportStartMsg for two-step initialization
3. Implemented handleExportKeys() for cancellation
4. Used context.WithCancel() for graceful termination

Concurrent Exports

Problem: Sequential single-VM exports blocked UI Solution: Designed concurrent multi-VM export system

Changes:

1. Added activeExports map for tracking multiple exports
2. Created activeExportState type for per-VM tracking
3. Implemented startConcurrentExports() and startSingleExport()
4. Created renderExportPane() and renderSingleExport() widgets
5. Implemented renderSplitScreenWithExports() for 60/40 layout
6. Modified validation flow to enable split-screen automatically

• Export progress persistence (survive app restart)
• Export queue save/restore (persistent queue)
• Cloud upload integration (S3, Azure, GCS)
• Compression options UI (gzip levels, algorithms)
• Checksum verification UI (SHA-256, MD5)

Code Improvements

• Unit tests for TUI components
