General

• Make tabbrowser extend tabbox?
• Field cleanup
• Arrowscroll extension and tab guts to be removed in re-theming
• Cleanup/remove close button binding
• Don't need the getComputedStyle check for RTL?
• API cleanup - not too much to part with

Adding tabs

• CPS is close to being the heaviest
• Clone generic tab vs. createElement+setAttribute
• Dispatching events
• Setting up scrollbars
• Session store not in play for single tab loads - painful for loading groups

Removing tabs

• Updating places commands/globalOverlay
  • goUpdatePlacesCommands very slow
  • Other command updates not as slow, but called nearly 70 times
• Dispatching events
  • dispatching 'select' event in tabbox for tabs/tabpanels very slow
• Session store again for removing a group
  • Have session store wait before recording
