Favourite Layouts

I have found on occasions I have lost all of my favourite layouts.

This has occurred when I have upgraded to a new PC or maybe when I have had file corruptions within windows for example with my desktop, profile., etc. 

I would like Sage to create a method where Favourites can be restored as they are not retained and you then have to add them all over again.

This is all well and good as many users probably only have a few different layouts but I am sure there are many like myself who have created various versions of layouts over the years and it can be a chore to go and find them again.
