Folders & First name of page - bug

As I wrote earlier, we need the option of creating folders and placing subpages that can be linked - this is the first thing.

The second thing is the problem with the name of the first page being generated. Regardless of whether the name is “index” or “admin” or “xxx.html” for example - “index” will be generated. The program will have a name that I will give it, but after generating the first page will always take “index”
