Smart Grid are really missing

Hello,

Having smart guides to align elements together when we drag them is really missing for us and would be a huge improvement for building nice looking cards. ( Snap Grid is not the solution and doesn't help) 

Here is an exemple, already using fabric.js : 

- github repo : https://github.com/mrflix/Alignment-Guides

- live demo : http://mrflix.github.io/Alignment-Guides/

Could we hope to have this implemented ? 

I can help if needed

Thanks a lot 

Pierre
