Create new view? or change clients to customer/view need to know how

I would like to create a new view and for the life of me, i can’t figure out how to?

So the url is as follows …/supplier/view

I would like to copy the invoice files so you could enter in supplier invoices writing to new tables. Changing the data values to write.

on another note what software does this forum use the interface is really easy to use?

Thank you in advance

or change the name of clients to customers/view for example that may be easier to answer
