+1 for this request as well.
I also have an idea similar to this for the flexible layouts. Creating flexible layouts with the add-on is awesome. It has become one of the most used features for my sites. However, it would be incredibly awesome to be able to reuse layouts. I’ve created a field group with 30 layouts in a group. It makes it so I can create less templates in wordpress. However, if I want to reuse any of those layouts in another field group, I have to recreate them from scratch. It’d be nice to separate this logic a bit so we can reuse the layouts similar to the reuse of field groups talked about above.
