Edit Template and Text with program?

Hello WordPress,

I have been working on a webshop for a while now, but the last edits I need to do, is too hard for me to find and edit.

I was wondering if there is a program that can read it all, so I do “Live edit”, where you can see the whole website, just like if you were on the site?

I got woocommerce installed on website.
– I tried to do it with Dreamviewer, but it can only show me the page design and setup on very few files.

I’m sorry for my bad english, I really hope some of you get it, and can help me out, it would be so great.

Best Regards
