TOPIC: Hide Category, and extra Contact field

Hi GREAT app.
I just have 2 questions:
1. Can you hide the Category field (if you only using 1 category, you don't need to have it specified)
2. I understand the you can't add extra contact field in the Light version, but can change eg "company name or Comment" to "Address", which would work, except, how can I make it a 'required' field?

Thank you

PS I am SO glad you can add different currencies. So many Joomla app's forget that Dollar and Euro are not the only currency out there

1. For LIGHT version you can hide category in price-list by editing source code only (/components\com_ipricecalc\views\price\tmpl\default.php)

2. You also can do it only by changing source code files in LIGHT version.
