[Feature Request] Support for headings in multiple markdown files

[aniketgm]

Description

Currently this supports showing headings only in current file. It possible to do that for multiple files.

Suggestion

• Specify scope as a parameter. For e.g.
  • Telescope heading scope=~/Document/MyNotes -- This will show headings of all markdown files in the folder specified.
• Now there are two scenarios:
  • Either the current folder user is in, is a git repo. So scope shall become Git root by default.
  • Or the current folder is some MyNotes folder (not git controlled), in that case, user should specify the folder / set keymap to call it respectively.

What are your thoughts ? Is this possible ?
