✓URL State Management: URLs function as built-in state containers that eliminate need for complex libraries like Redux or MobX, providing persistent shareable state without additional dependencies or configuration overhead.
✓Automation ROI Formula: Calculate automation value using: (task value × iterations) minus (automation effort + maintenance costs + documentation costs + mistake costs) plus or minus long-term effects to determine worthwhile automation targets.
