Template question

[A Hot Mess]

Total noob. First post.

I've been meaning to get started working on a Zen Cart install for quite a while now. I keep putting it off as it just looks to be an overwhelming task each time I start to breakdown what I need to do. It seems so much less straightforward than something like Wordpress, where templating and customization is very user-friendly.

I've decided to finally bite the bullet though. I'm going to customize this cart, even if it kills me.

Ok.

As barco57 mentioned, ZenCart pages do seem to be "cobbled together" from many various files and stylesheets. Is there (possibly) a map or grid identifying where sections of various pages (mainly the home/main/index page) can be edited? Ya know... "this section is edited in file 'x'"... "this blurb can be edited in the admin area"... etc. An example would be like the attached image.

Does something like this exist? Or.. is it not even that simple?

Thanks.
