Creating invoices with subtotals at the bottom instead of the top - Also the glitch with money values looking like $146.720000 - Any solutions for this yet?

I know these things are in the pipeline for Halo, but does anyone know of any solutions for invoices showing subtotals of things such as "Taxes" showing up under the list of various taxes instead of the subtotal showing on top of the line items?

Also, does anyone have a solution for the weird additional digits that show up randomly on some $ amounts?

HTML only allows us to pull large fields of data but it won't let us manipulate the data after it's pulled. I would need javascript for that which I don't believe the engine allows for.
