Decent app, needs some additional features

So, far pretty happy with this app, but... No apparent ability to remove a product from an invoice after invoice created - definite must have for future release, ability to remove product from invoice. Also, have ability to create a product description, but doesnt show up on the actual invoice? This is another must have... not much point in being able to have a product description if it doesnt show on the invoice...

More ability to customize invoice templates, move notes location, or have separate note sections for default notes, customer notes, and move to left of total pricing section at bottom...
