Numbered lists in sidebar

[djkeh]

as-is

Flybook currently treats document filenames to titles in sidebar. There's a slight change of naming happening at this moment, and it figures out like:

• 1._sample_doc.md -> 1 Sample Doc
• 1.-sample-doc.md -> 1 Sample Doc
• 1_-_sample_doc.md -> 1 Sample Doc

It seems like one of the policies to handle blanks and special characters.

to-be

This issue suggests to put numbering at the head of each titles(by simply accepting dot(.)), and it might look like:

• 1._sample_doc.md -> 1. Sample Doc

This issue is to examine whether the idea above is possible, and implement the feature if possible.
