Hide and serialize question #17

Hi,
I just started to learn your library and have some questions:

• a common use case is to hide some elements on the smaller screen and show them on a bigger screen
• next use case is to differently reposition elements depending on different screen sizes
• the last question is how to serialize grid (for example to json) so I can load (deserialize) it later

What I would like to achieve is to let user reposition elements depending on screen size and to save that configuration and later to load that configuration (or even enable user to save many different configurations and load them as needed)
Is this achievable with gridifier?
Thanks in advance for any hint!
