Hi Ashley,
Have you guys ever think about adding "Run from the first layout" button? That would make my (and many others I believe) life so much easier. I always have to start testing from the first layout cause of initial settings which are done there, and I usually forget to switch to the first layout before I run the preview. And it is pretty annoying that I must switch to the first layout every time I want do to a preview.
Let me know what you think about it.
Thanks.
