Just release a new version for my Ko! Custom Gift Certificate v1.4.0
We have now the choice to put a expiration date, the purchase date, both or none.
Also don't forget you can modify the color, font, size and position of each label and value on a card.
All that in the /components/com_kocustomgiftcard/assets/params/default.xml
For those who already make change in the old card_params.xml, I change the name of the xml in this new version (default.xml). Don't forget to apply your change in the new file.
