Provide the element to tack, not the ID

[aemonge]

Is it posible to tack an element by passing the element it self instead of it's ID ?

This would be specially useful for Apps developed in Polymer/WebComponents

I wanna do this as well and looked into the code. Currently not possible, and it's not entirely trivial to fix either as several functions deep depend on the id as a string being present.
