Is your feature request related to a problem? Please describe.
Besides add/delete md files, I expect the linebyline can do some simple file management like moving a md file to another folder or duplicating a md file for revision.

Describe the solution you'd like
add "move md file" and "duplicate md file" with add/delete md files

Describe alternatives you've considered
