Tab Navigation Update

✅ Improvements Complete

1. Tab Navigation Keyboard Shortcuts

Added three new keyboard shortcuts for tab navigation:

  • Tab - Next Tab (cycles forward through active tabs)
  • Shift+Tab - Previous Tab (cycles backward through active tabs)
  • t - Tab Menu (shows available tabs in subtitle for 3 seconds)

2. Default View Changed to Simplified

The Overview tab now defaults to the simplified view without subflow rows:

  • Only shows main flows (no nested frame type breakdowns)
  • Cleaner, less verbose display
  • Toggle with v to see detailed view with subflows

  • Active tab: Blue background (#0080ff) with white bold text
  • Inactive tabs: Dark background with gray text

  • Tab bar: Located at top of flow table area with 3-row height
