UI Improvements Implementation Summary

Overview

Successfully implemented UI/UX enhancements to SKiTCH Controller following the standard approach recommendations. All changes focus on improving visual hierarchy, accessibility, and user experience while maintaining the compact, efficient design.

Changes Implemented

1. Design Tokens System ✅

File: src/styles/designTokens.ts

Created a comprehensive design tokens file with:

  • Semantic color system - primary, success, warning, danger, info, neutral
  • Button classes - Reusable styles for all button variants
  • Typography scale - Defined heading and body text sizes
  • Spacing scale - Consistent gaps and padding
  • Alert classes - Status box patterns

Impact: Provides a single source of truth for design consistency across the app.

2. Enhanced Button States ✅

Files Modified:

  • src/components/ProgressMonitor.tsx
  • src/components/MachineConnection.tsx
  • src/components/FileUpload.tsx
  • src/components/ConfirmDialog.tsx

Improvements:

  • ✅ Rounded corners - Changed from rounded to rounded-lg for softer appearance
  • ✅ Better padding - Standardized to py-2.5 for comfortable click targets
  • ✅ Hover effects - Added hover:shadow-lg for depth
  • ✅ Active press feedback - Added active:scale-[0.98] for tactile feel
  • ✅ Focus rings - Added focus:ring-2 with color-matched rings for keyboard navigation
  • ✅ Disabled states - Clean opacity change, no grayscale filter
  • ✅ Active states - Added active:bg-{color}-800 for click feedback
  • ✅ Smooth transitions - duration-150 for responsive feel

Before:

className="px-4 py-2 bg-blue-600 text-white rounded hover:bg-blue-700"

After:

className="px-4 py-2.5 bg-blue-600 text-white rounded-lg font-semibold text-sm
  hover:bg-blue-700 active:bg-blue-800 hover:shadow-lg active:scale-[0.98]
  transition-all duration-150 cursor-pointer
  focus:outline-none focus:ring-2 focus:ring-blue-300 focus:ring-offset-2"

3. Improved WorkflowStepper ✅

File: src/components/WorkflowStepper.tsx

Visual Enhancements:

  • ✅ Larger step circles - Increased from w-8 h-8 to w-10 h-10
  • ✅ Gradient progress bar - from-green-500 to-blue-500 shows completion visually
  • ✅ Better completed state - Green circles with check icons
  • ✅ Enhanced current state - Ring effect with ring-2 ring-blue-300
  • ✅ Improved shadows - Color-matched shadows (shadow-blue-600/40)
  • ✅ Thicker progress line - Changed from h-0.5 to h-1

Accessibility:

  • ✅ Added role="navigation" and aria-label="Workflow progress"
  • ✅ Progress bar has role="progressbar" with aria-value attributes
  • ✅ Each step has role="listitem" and aria-current="step" for current
  • ✅ Step circles have descriptive aria-label with state info

Impact: Clearer workflow visualization with green showing completion and blue showing current/upcoming steps.

4. Enhanced Color Blocks in ProgressMonitor ✅

File: src/components/ProgressMonitor.tsx

Visual Improvements:

  • ✅ Larger color swatches - Increased from w-5 h-5 to w-8 h-8
  • ✅ Better borders - rounded-lg instead of rounded
  • ✅ Enhanced shadows - Added shadow-md to swatches
  • ✅ Ring effect on current - Dynamic ring color for active thread
  • ✅ Improved layout - Two-line thread info (name + stitch count)
  • ✅ Larger status icons - Increased from w-5 h-5 to w-6 h-6
  • ✅ Animated current indicator - Added animate-pulse to arrow
  • ✅ Better progress bar - Taller (h-2) with rounded ends
  • ✅ Clearer states - Different border colors and backgrounds

Accessibility:

  • ✅ Added role="listitem" to each color block
  • ✅ Comprehensive aria-label with thread number, count, and status
  • ✅ Color swatch has aria-label with hex color
  • ✅ Progress bar has role="progressbar" with aria-value attributes
  • ✅ Status icons have aria-label for screen readers

Impact: Thread colors are now much easier to see, and the current block is clearly indicated.

5. Accessibility Enhancements ✅

ARIA Labels Added:

  • ✅ All buttons have descriptive aria-label attributes
  • ✅ Progress bars have role="progressbar" with value attributes
  • ✅ Workflow stepper has proper navigation role
  • ✅ Color blocks have detailed state information
  • ✅ Dynamic labels update based on context

Focus Management:

  • ✅ All interactive elements have visible focus rings
  • ✅ Focus rings use color-matched styling
  • ✅ focus:outline-none with custom ring for consistency
  • ✅ Ring offset for better visibility

Keyboard Navigation:

  • ✅ All buttons are keyboard accessible
  • ✅ Tab order follows logical flow
  • ✅ Focus states clearly visible

6. Typography Improvements ✅

Text Sizes:

  • ✅ Maintained minimum 12px (text-xs) throughout
  • ✅ Body text at 14px (text-sm)
  • ✅ Headings properly sized (text-lg, text-xl, text-2xl)
  • ✅ Consistent font weights (semibold for emphasis)

Readability:

  • ✅ Proper line height on multi-line text
  • ✅ Color contrast meets WCAG standards
  • ✅ Hierarchical sizing for scanability

Files Modified

  1. ✅ src/styles/designTokens.ts - Created new design system
  2. ✅ src/components/ProgressMonitor.tsx - Enhanced buttons, color blocks, accessibility
  3. ✅ src/components/WorkflowStepper.tsx - Improved visibility, states, accessibility
  4. ✅ src/components/MachineConnection.tsx - Updated button styles
  5. ✅ src/components/FileUpload.tsx - Enhanced upload button
