[Feature Request] When saving the file do it without white spaces

[ovigia]

By the title of the issue i mean something like this:

Right now the files are saved like so - "This is a webpage i want to save.html"

Would be great if by default the page was saved like so - "This_is_a_webpage_i_want_to_save.html

Been using Asciidoctor | A fast, open source text processor and publishing toolchain for converting AsciiDoc content to HTML5, DocBook, PDF, and other formats. for all my research and note taking and it's quite annoying having to do it by hand.

thank you
