Customisation of directory submitter (bought with Master Resell rights)

I bought? a directory submitter visible on [[login to view URL]][1] And I now have the master re-sell rights but I don t know how to customise the software to give it a new name or change a few colors to make it loo different from the original one. I do not need a lot of work to be done, I mainly need to change the software's names and the layout so it is seen as a different product than the original when presented. Waiting for the best offer to get started !
