Don't we also want to show feedback when pressing the right button (in
preparation for showing the history menu on the back button, for instance)?

[bruthig, 2015/08/20 20:35:35]

That will be triggered by the AnimateToState(ACTIVATED) in the
ToolbarButton::ShowDropDownMenu() method.

[jonross, 2015/08/19 22:13:36]

Do you need to check the exclusivity of these clicks?

Event::IsOnlyLeftMouseButton / IsOnlyMiddleMouseButton

[bruthig, 2015/08/20 20:35:35]

Negative, actions are still triggered when a button is released while both the
left and middle buttons are pressed. Specifically if the user left clicks and
holds and the animation proceeds to a long press on the "Back" button and then
they middle click and release, then the most recent url in the history is
brought up in a new tab.  This is equivalent to a simple middle click and
release on the "Back" buttonm so IMO it should show an ACTION_PENDING ->
QUICK_ACTION animation sequence which this allows for.

Consider refactoring these animations to be around the if block. Moving the
result early exits outside as well.
