+# Maneuver Dialog Implementation Progress
+
+## Overview
+
+Implementing a comprehensive modal dialog for creating, editing, and managing spacecraft maneuvers with real-time orbital preview and Hohmann transfer calculations. The dialog provides an intuitive interface for planning orbital maneuvers with immediate visual feedback.
+
+## Completed Tasks
+
+### Phase 1: Foundation (Complete)
+- [x] Add ManeuverDialogState to ui_renderer.h
+- [x] Extend UIState with maneuver_dialog field
+- [x] Add maneuver_list_active and maneuver_list_scroll to UIState
+- [x] Create render_maneuver_dialog() skeleton
+- [x] Add tab bar widget
+- [x] Test dialog open/close with "Create Maneuver" button
+
+**Commit:** `9c55c7c` - feat: Implement maneuver dialog Create tab (Phase 2)
+- Implemented complete Create tab workflow for maneuver management dialog
+- All Phase 1 foundation work included in this commit
+- Dialog opens/closes from maneuver list button
+
+### Phase 2: Create Tab (Complete)
+- [x] Implement render_maneuver_create_tab() skeleton
+- [x] Add all input widgets (spacecraft, name, direction, delta-v, triggers)
+- [x] Implement update_orbital_preview() using preview_burn_result()
+- [x] Implement render_orbital_preview() to display results
+- [x] Add validation logic with validate_burn_parameters()
+- [x] Implement create_maneuver_from_dialog() using add_maneuver_to_simulation()
+- [x] Test create workflow end-to-end
+
+**Commit:** `9c55c7c` - feat: Implement maneuver dialog Create tab (Phase 2)
+- Complete Create tab workflow with all input widgets
+- Real-time orbital preview with color-coded validation
+- Integration with add_maneuver_to_simulation()
+
+**Supporting Commit:** `5ecd880` - feat: Add maneuver UI control functions
+- add_maneuver_to_simulation(): Add maneuvers dynamically
+- preview_burn_result(): Preview orbital elements after burn
+- validate_burn_parameters(): Validate burn parameters
+- calculate_hohmann_transfer(): Calculate optimal two-burn transfer
+
+### Bug Fixes (Complete)
+- [x] Fix segfault at ui_renderer.cpp:503
+- [x] Fix widget type for input boxes (GuiValueBoxFloat)
+- [x] Add conditional rendering for dropdowns
+
+**Commit:** `351f647` - fix: Initialize UIState maneuver_dialog fields properly
+- Fixed segfault by proper initialization of all ManeuverDialogState fields
+- Dialog now opens and runs without crashing
+
+**Commit:** `2874c5e` - feat: Add auto-generated maneuver names with edit capability
+- generate_maneuver_name() creates sensible names automatically
+- User can still manually edit names if desired
+
+**Commit:** `f45b111` - fix: Add conditional rendering for GUI dropdowns
+- Wrapped GuiDropdownBox calls with validity checks
+- Dropdowns only appear when spacecraft is properly selected
+
+## In Progress
+
+None currently
+
+## Pending Tasks
+
+### Phase 3: Hohmann Tab
+- [ ] Implement render_maneuver_hohmann_tab() skeleton
+- [ ] Add body selector widgets
+- [ ] Implement calculate_hohmann_for_dialog() using calculate_hohmann_transfer()
+- [ ] Display Hohmann results
+- [ ] Implement create_hohmann_burns() to add both maneuvers
+- [ ] Test Hohmann workflow
+
+### Phase 4: Edit Tab
+- [ ] Implement render_maneuver_edit_tab() skeleton
+- [ ] Load existing maneuver data into fields
+- [ ] Lock spacecraft field
+- [ ] Implement update_maneuver_from_dialog()
+- [ ] Add delete confirmation dialog
+- [ ] Test edit and delete workflows
+
+### Phase 5: Enhanced Maneuver List
+- [ ] Modify render_maneuver_list_ui() for selectable items
+- [ ] Add maneuver preview panel to list
+- [ ] Add action buttons (Create, Hohmann, Edit, Delete)
+- [ ] Connect buttons to dialog
+- [ ] Test enhanced list interaction
+
+### Phase 6: Polish
+- [ ] Add keyboard shortcuts (Enter to confirm, Escape to cancel)
+- [ ] Improve error messages
+- [ ] Add tooltips for complex fields
+- [ ] Handle all edge cases
+- [ ] Test with various configurations
