Currently, we can import a file graph to a DB graph, but when you export the DB graph as MD files, what you get is not a file graph but several MD files with Logseq syntax.
If you make changes to those exported files and want the changes in your DB graph, then there is nothing you can do other than add the changes manually.
This is extremely useful when you are hosting a small docs folder in your git repo. I know we can use a file graph for it, but we both know the main focus will shift to the DB graph; for me, it is good to have that option as well.
And I hope for the MD export, we can also have the option to export MD files marked with “publish” without Logseq syntax; currently, that only affects HTML.
