From 5e8c00f577567586eb7730e815e3c291bf8be4e6 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 20 Nov 2025 16:46:52 +0000 Subject: [PATCH 01/16] feat: implement Pro SaaS UI redesign with high-density layout - Add Space Mono and Inter fonts for professional typography - Create ProBillSplitter component with fixed-frame app shell layout - Implement CSS Grid-based ledger with sticky columns and shadows - Add tile-based user assignment interaction system - Implement keyboard navigation (arrow keys, Enter, Space, Escape) - Create Breakdown view with share graphs and settlement visualization - Add right-click context menu for item actions - Implement person editor modal with color theme selection - Add custom minimal scrollbars matching Pro design aesthetic - Update Person interface to include colorIdx for consistent theming - Ensure backward compatibility with migration logic for existing bills - Apply slate-based monochrome color palette with user-specific colors - Implement z-axis layering system (header z-20, grid z-10, sticky headers z-30, footer z-40) Design follows "Financial Tool" aesthetic with: - Inter font for UI/labels (high readability at small sizes) - Space Mono for data/numerals (fixed-width for vertical alignment) - Strict monochrome base with color only for data/users - Fixed 6-color palette for user identity - Glassmorphism header with backdrop blur - Keyboard-first interactions for power users --- app/globals.css | 112 +++++ app/page.tsx | 632 +---------------------- components/ProBillSplitter.tsx | 894 +++++++++++++++++++++++++++++++++

From 806ed655bf300399688c93247fa381ad31e84d39 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 21 Nov 2025 05:58:00 +0000 Subject: [PATCH 04/16] fix: resolve critical text input focus loss bug **Problem:** All editable grid cells (item name, price, qty) were losing focus after typing one character, making text input impossible. **Root Cause:** GridCell component was defined inside ProBillSplitter. Every state update caused ProBillSplitter to re-render, which redefined GridCell as a new component. React saw it as different and unmounted/remounted the input, losing focus. **Solution:** - Moved GridCell component outside ProBillSplitter function - Wrapped with React.memo for performance - Updated all GridCell usages to pass required props: - isSelected, isEditing (computed states) - onEdit (update callback) - onClick (selection callback) - editInputRef (focus management) **Verified:** All other inputs (title, tax, tip, discount, bill ID, person name) are simple controlled inputs and work correctly.

Click cell or navigate with arrows/tab 2. Start typing → auto-enters edit mode 3. Type your value 4. Press Tab/Enter/Arrows → saves and moves to next cell 5.
