Tabtastic 2 Requirements

This page is a collection of requirements for the third generation Chrome tabstrip implementation.

• live tab contents during dragging
• full size dragged representations
• frame fade transition during detach/attach
• dragged representation places tab at relevant position in tabstrip (from jar)
• ability to resume drag in tabstrip after attach
• ability to resume drag in tabstrip after move from overflow UI
• overflow UI capability
• multiselect for drag and close
• independent continuous animations (View::GetAnimator)
• generic TabStrip baseclass that does not deal with TabContentses
• BrowserTabStrip subclass that interacts with TabStripModel (and knows about TabContentses)
• testing for Layout
• general testable interface (View-Controller separation)
• tests for drag and drop using testable interface
• windows 7 integration for drag and drop targets at screen edges in lieu of the current Dock system that we use on Vista and below.

P2s/3s:

• pinned tabs
• tab coloring

Implementing a system capable of supporting all of this will require some tweaks to TabStripModel and a replacement of the existing Tab/TabRenderer/TabStrip/etc system.

We should avoid adding new features/capabilities to the current tabstrip until this system is implemented
