>    As you know, I've been working    on layouts for Spec 2. The basic layouts I want to have available next week(s) are four: 
> 
>    * +SpecBoxLayout+ : A simple way to place components horizontally or vertically 
>    * +SpecPanedLayout+ : Same as box layout, but with a resizable splitter (and it will allow just two... if you want more you will need to compose).
>    * +SpecGridLayout+ : To place components in a grid (x,y coordinates and spans)
>    * +SpecXYLayout+ : This could be renamed as +SpecAbsoluteLayout+ and it's name says all, it will allow absolute location of components (obviously, in relation with its parent).

Apple and others call it auto layout. I don‘t like that name as it isn‘t really clear. It could be called ConstraintLayout.
