 🐛 **Current Bugs:**
 - Tab indentation handling still uses feedkeys and needs refactoring
 - Shift-Tab behavior may not be consistent with spaces vs tabs
+- Enter key (<CR>) handling has several issues:
+  - Doesn't properly handle empty lines after TODO items
+  - Cursor positioning can be incorrect in some cases
+  - Outdenting behavior is inconsistent
 - Edge cases with mixed indentation (spaces + tabs) not fully handled
-- Cursor positioning could be improved in some scenarios
+- Cursor positioning could be improved in several scenarios
+- Debug output is currently only enabled for Tab/Shift-Tab but not other operations
 
 ## Roadmap
 
 📌 **Planned Improvements:**
 - [ ] Refactor tab indentation to use proper buffer operations
+- [ ] Fix Enter key handling for all cases
+- [ ] Add consistent debug output for all operations
+- [ ] Improve cursor positioning logic
+- [ ] Handle empty lines and edge cases better
 - [ ] Add support for numbered lists
 - [ ] Add support for nested TODO items with proper indentation
 - [ ] Add visual selection operations for multiple TODOs

+## Debugging Recommendations
+
+To help diagnose issues, you can:
+
+1. Add `debug_line()` calls to key functions like `press_enter()`
+2. Create a debug mode that can be toggled via:
+   ```lua
+   local debug_mode = false
+   ```
+3. Make debug output more structured with timestamps and operation types
+4. Log cursor positions before/after operations
+5. Add validation of line states after modifications
+
+Example debug output format:
+```
+[DEBUG] [TIMESTAMP] [OPERATION] 
+  Line: 42
+  Before: {indent="  ", marker="-", is_todo=true}
+  After: {indent="    ", marker="-", is_todo=true}
+  Cursor: {lnum=42, col=6} -> {lnum=43, col=4}
+```
