See Handout for Screenshots
What We Expected out of HE
It was too simple, not enough features
Problems mostly with Watchlist
Help, Buy/Sell Screens Potential Trouble

Major Changes
  • Popup Menus to Focus Screens

HE Popup menus violate Palm standards
Switch to focus screens instead
Slightly slower than a popup menu
More detail on the selected stock
Consistent with Palm standards

  • Watchlist Nested Tabs

Nested Tabs inconsistent with Palm standards
Switching screens more consistent
Less screen real estate and clutter
No restraints on category names or quantity
Merged with the Recent cache on Quotes page
