1) It would be great to have a link to "Re-edit" when you're customizing a theme after you go to preview. If you don't like the preview, it seems that the only way back to the html code is via several steps.
2) Whenever I go into "preview," it always go to the "about" page which is not usually where I need to preview. If that was adjustable, it would also save time.
Thanks for considering!
This isn’t something that we have planned at the moment - however the preview button will now go to the page you were editing.
