Compatibility with github

hi, first of all I want to congratulate you for this wonderful software. For some time I was looking for something like that and after thousands and thousands of software, I found it!

Going back to the reason why I'm here, I was thinking that it would be a good idea for the program to allow choosing:
* The extension of each document that you save.
* The path of a main document and all the subdocuments are saved in the same path.

This idea is to use the program in a way that is compatible to create pages in GitHub and synchronize them, without the need to include personal notes.

I would like to read what users think about this idea, and maybe, we need to improve it.
