Extension system: - Simple Invoices finally has an extension system! its long overdue and will help push Simple Invoices further - The extension system is very basic but works as expected -- for details on how it works and how to create extensions refer ( http://simpleinvoices.org/wiki/extensions_faq ) - The main aim of Extensions is to enable easy development of alternate ideas for Simple Invoices and enable an easy way to distribute them -- previous if a new developer wanted to try something different they would have to do it outside of svn or their own private branch in svn --- which is overly complex and slows things down -- now developers can create a new extension to test out whatever ideas they want - if its good it'll go in Simple Invoices else it'll be available to everyone as an optional extension - also Extensions provide an clean way to create customisation of Simple Invoices to suit whatever purpose
There are currently 2 extensions in development - 1 adds some much need ajax actions and allows for editable unit_cost and unit_price in invoice creation -- alot of people have asked for it for along time but its actually happening now - the other tranasforms Simple Invoices into a School Management System
Zoho invoices - you might of seen on techcrunch that Zoho released an invoice app - adds to the list of web2.0 style invoice apps around - only thing of interest is their invoice template - looks very familiar :) -- slide 11 in their product spiel thing
