Better functionality Rated 3 out of 5 stars

It could use Split Browser's arrows instead of a toolbar button, seeing as pressing a button and THEN having a tile is less useful than drag/dropping a link on a hotspot marked by a transparent, fade-in arrow. Pull this off and I'm all in!

This review is for a previous version of the add-on (1.5.1-signed). 

Already implemented!

Tile View already has the ability to drag-and-drop a link, bookmark or tab to open in a new tile. Just use Ctrl+Drag.
