Good so far

I like and appreciate the plug in and use it daily. However, there is one serious issue – the most recently modified data is lost from an Invoice when I view it (View button on the Edit|Invoice page). This happens consistently, even after updating the page. The workaround is to choose Invoices on the Dashboard and then return to the Invoice. This retains the most recent data. However, it takes extra time and is especially inconvenient when you forget, lose your data and have to re-enter it. If you contact me via email I will be happy to replicate the issue and provide details such as php version etc.

I would also like more control over printed Invoice layout, but it appears you have the solved with your paid upgrades.

Overall, a very good plug in.
