I feel that a handy feature is missing even can't able to give line breaks without HTML tag. I had an trouble while adding long description or try to add tables on my invoice/Estimate. Why can you add WYSIWYG or Tinymce editor for the following
1. Invoice & Estimate description
2. Invoice terms & Estimate Terms
3. Invoice & Estimate notes
And new invoice template or the latest non-saas version invoice & Estimate UI is required badly. The existing layouts are too messy.
