1. Icons/Emojis for Trades & Specialties

Request: Add a "Trade Icon" field to each cost code or line item, auto-filled based on trade category. Show icons in estimate views, proposal views, PDF exports, and Gantt/timeline views by trade.

Right now line items are text-only. Adding visual trade icons (like a hammer for carpentry, lightning bolt for electrical, water drop for plumbing, etc.) would make estimates and proposals much easier to scan — especially for clients reviewing them. Think of how Home Depot visually distinguishes trades in their skilled trades materials.
