I appreciate the frustration.
Also if you want to run a small function on scene load for your documents you can reset the margin value which is making the scene sit in the centre of the page. (saves you having to re-open and remove positioning)
document.getElementById(hypeDocument.documentId()).style.margin = "0";
What this does is get the id of your Hype document and sets the margin value to 0px instead of the default auto. Thus, your document should now set itself in reference to the top / left of the screen.
