Stage 1: Definition

1. Feature overview

When dragging tabs on the tab bar, we should show the tab and animate when you rearrange them, instead of showing a placeholder indicator like we currently do. We should also show a thumbnail of the page on detach operations, and make sure we have a good threshold, so this isn't triggered accidentally.

This feature falls primarily in the Experience category (from the "Discover, Experience, and Connect" vision statement.)

We're making this change because:

• It's a 1:1 representation of what will happen when you drag a tab, and makes it clearer which action you're actually performing.
• It also makes it easier to see when you're moving tabs vs. detaching.
• Also, it's pretty ;)
