Be able to name notes / documents

Hi! I'm using HackMD to try and sync with a few Markdown pages in a Hugo repo. Because of the formatting for the Hugo doc at the docs appear as "Untitled" - which makes it difficult to open the right one to edit on the first try. It'd be great to be able to use a filename separate from an H1 header / etc. - in my case even the name of the file as I'm linking it to GitHub would be perfect.
