## 2026-01-24 - [CLI Visual Hierarchy]
**Learning:** UX principles like visual hierarchy and semantic coloring apply equally to CLI tools. Using ANSI codes and emojis transforms a wall of text into a scannable dashboard.
**Action:** For future CLI tools, prioritize a `Colors` class or library early to establish a visual language (Green=Success/Buy, Red=Failure/Sell).
## 2024-05-22 - Visual Hierarchy in CLI Output
**Learning:** Adding color-coded indicators (Green/Red) and emojis (💰, 📉) in CLI tools significantly reduces cognitive load when parsing financial data streams. It transforms a wall of text into a scannable narrative.
**Action:** For data-heavy CLI applications, always implement a semantic color system and visual anchors (icons/emojis) for key events.
