Possibility to add discount % / row.. maybe even possibility to edit the "total" row for each line and the deducted ammount would be translated in to xx% discount for that line.

.possibility to choose attribute of product missing.

oh and "pdf end note" field just refuses to center text for me.. (solved with adding a table and making it 100% wide and centerd text in that instead..

Hello,

1) as regards product attributes, these can be defined -- however, only manually by clicking "add attributed" in the item row.

2) Centering: this depends on what does the TCPDF library support. Did you try using style only or did you use <center> tags?

3) The pricing options currently copy VirtueMart possibilities. Thanks for the idea though. We will consider adding more options in some of the next releases.
