I've just uploaded a preview of the next beta (Beta 2) release of Simple Invoices
Also as a result of the Dec 08 vote - http://www.simpleinvoices.org/roadmap/vote#december_2008_vote there have been some changes to invoice creations. Basically me and 2 other people are the only ones using the Total style invoices :( - most other people uses Itemised and the rest use Consulting (note: theres been a late charge in the votes for Consulting).
What this means for you is when you click New Invoice it'll default to Itemised style - if you want to add in notes per line item (consulting style) just click the 'Notes Add' to the right of the Unit Price heading and all the description fields will be displayed. How Total style will be selected is stilla work in progress.
Whats new since beta 1?
