Things I need in Zoho Books

Hi,

I'm very happy with Zoho Books but I would like these ideas implemented someday:

• "Sales by User" reports! (For allocating Sales commissions)

• Individual "Signature" template for each User (So each user can have his/her respective contact details when emailing Estimates and Invoices)

• User restrictions so that normal Users can't delete invoices!!, contacts, etc.
(Actually, many Accounting Softwares don't allow the deletion of Invoices created... It's strange that we can in Zoho Books...)

Thanks
