Better Editor Design and Mobile support

Hello!
I have been spending quite a bit of time in the Editor to customize the invoice template and it's getting really frustrating. I was wondering if there will be an update when the new 8.1 Beta becomes available to be able to use the free form feature?
The issues I'm having is after I add additional fields to the line item, the width of the page size increases over the page border.
The additional field is a thumbnail picture of the product and description that goes below the product name. Even though these sections are short and small, the width expands way past the totals section.
Secondly, can we possibly see a mobile version of this feature to make invoices while at job sites when we have no access to computer or tablet?
Thanks!
