Invoice in CRM is crippled?

Invoice in CRM is crippled?

I think the invoicing in zoho CRM is lacking too many features to be usable.

Issues I'm running into are:
  • Invoice address is not automatic filled with the customer billing address
  • Invoice date is not filled in with default date of today
  • Product description is not filled in with the description of the product
  • Product description is collapsed by default, need to click it open for every row
  • Taxes are not automaticly calculated
  • When you select a product with a price table that has a discount, you get a weird row.. You will see the default price and the subtotal will be calculated with the discounted price, will look like this: 100 units x $10 = $8.000. 
In this state the invoicing is really not usable. Can't the zoho invoice be really integrated into zoho crm?
