* Literature Review
** Org Mode Studies
*** "Org Mode as Knowledge Management System" :paper:
**** Abstract
This paper explores the use of org-mode for personal knowledge management.

**** Key Findings
- Structured text improves information retrieval
- Hierarchical organization aids comprehension
- Plain text format ensures longevity

**** Methodology
The study involved 50 participants using org-mode for 6 months.

***** Data Collection
- Weekly surveys
- Usage analytics  
- Interview sessions

***** Analysis
Statistical analysis revealed significant improvements in:
1. Information organization
2. Task completion rates
3. Note-taking efficiency

*** "Tree Visualization of Hierarchical Data" :paper:
**** Research Question
How do different tree visualization methods affect user comprehension?

**** Experiments
***** Experiment 1: Static vs Interactive Trees
Interactive trees showed 23% better comprehension scores.

***** Experiment 2: Vertical vs Horizontal Layout
No significant difference in comprehension, but users preferred vertical layout.

* Data Analysis
** User Feedback
*** Survey Results
**** Satisfaction Ratings
- Ease of use: 4.2/5
- Visual clarity: 4.5/5
- Performance: 3.8/5

**** Common Requests
1. Better mobile support
2. Collaborative editing
3. Integration with other tools

*** Usability Testing
**** Task Completion Times
***** File Import
Average: 12 seconds (target: < 10 seconds)

***** Node Editing  
Average: 8 seconds (target: < 5 seconds)

***** Export Function
