Invoice PDF for Clients IN project

Ok, we love the invoice module and are using it heavily and while we know its an early version of the project I would like to throw in a feature request.

Situation: Invoices can be sent to the client when generated via email but there are times when they would like a copy later. We started generating the PDF version and uploading to the FILES section of the project.

The client likes that this is available but it got me thinking about the duplication of effort and extra file space (and extra step in invoicing)

Concept: When an invoice is generated for a project, could an 'invoicing' tab show up in the project. This tab would display the related invoices and a link to view/download pdf. Obviously permission elements would allow admin to control access to this tab based on the user roles.

I was thinking it would be a very basic tab. Just show invoices ordered by date, could show payment status (paid, late etc) and if your role had access to the full invoice tool, the invoice number could be linked back to the invoice module for quick access and editing.

Didnt expect any, just wanted to toss this out in case it was worthy of further discussion.
