-# Project Progress
+# Progress Update
 
-## Completed Work
-- Initial Memory Bank setup
-- Basic Plan/Act mode system implementation
-- Mode persistence with JSON storage
-- Simple event callback system
-- Status line integration
-- Basic mode toggling (`<leader>tm`)
+## Current Status
+Working on mode_manager plugin implementation with enhanced state management.
 
-## Recent Changes
-- Rolled back to v0.1.0 (commit 57f551e)
-- Created backup branch of pre-rollback state
+## Completed Tasks
+1. System rollback to v0.1.0
+   - Created backup branch
+   - Successfully rolled back to stable version
+   - Preserved previous state
+
+2. Architecture Planning
+   - Defined enhanced mode state management system
+   - Documented implementation phases
+   - Established integration patterns
 
 ## In Progress
-- Verifying system stability post-rollback
-- Reassessing implementation priorities
-- Evaluating core functionality
+1. Mode Manager Plugin Implementation:
+   - Converting mode_manager.lua into proper plugin structure
+   - Setting up initialization hooks
+   - Implementing state persistence layer
+   - Adding event system foundations
+
+2. Integration Work:
+   - Configuring plugin specification in init.lua
+   - Setting up custom_statusline integration
+   - Implementing mode-aware functionality
 
 ## Next Steps
+1. Complete core state management implementation
+2. Add event system with hooks and queuing
+3. Implement persistence layer with versioning
+4. Set up plugin and UI integration components
 
-### Phase 1: Post-Rollback Stabilization
-- [ ] Verify core functionality
-- [ ] Document differences from rolled back state
-- [ ] Reassess implementation priorities
-- [ ] Review backup branch for salvageable improvements
-
-### Phase 2: Core State Management
-- [ ] Implement mode-specific settings store
-- [ ] Add mode context preservation
-- [ ] Create mode initialization hooks
-- [ ] Add state validation system
-- [ ] Implement error recovery mechanisms
-
-### Phase 3: Event System Enhancement
-- [ ] Add pre-mode-change hooks
-- [ ] Implement post-mode-change hooks
-- [ ] Create event queueing system
-- [ ] Add mode-specific event handlers
-- [ ] Implement async event processing
-
-### Phase 4: Integration Features
-- [ ] Add mode-specific colorschemes
-- [ ] Implement mode-specific keymaps
-- [ ] Create mode-specific status line content
-- [ ] Add mode-specific buffer handling
-- [ ] Implement window layout persistence
-
-## Known Issues
-- Current state persistence is basic
-- No validation of stored state
-- Limited error recovery options
-- No mode-specific settings
-- Basic event handling system
-
-## Future Considerations
-- Custom mode creation system
-- Mode-specific plugin configurations
-- Advanced state synchronization
-- Mode templates and presets
-- Mode groups
-- Mode transitions animations
-- Mode-specific help system
+## Technical Requirements
+- Proper plugin specification format
+- Local plugin integration
+- Correct module initialization
+- State persistence mechanisms
+- Event handling system
+- Integration interfaces
