Payment Method develp problem

[leandroimw]

Hi !

I have a big problem. I'm develop a new payment method, the header of my manifest.xml is <extension version="2.5" type="plugin" group="vmpayment">
and I can't add new buttons on Order Lists page. The payment process is OK but I need add functions on Order lists but I can't.  How can I do that?

I try creating other plugin but this is not a solution for me because I need configuration parameters of the payment method.

I appreciate your help!
