+1 Please! I have almost 20,000 notes that I exported from OneNote into *.md files and am text-cleaning them as I use them. I want to move the cleaned files into the folders I’ve created in my vault (BUS, DEV, HOME, etc.)
I get that I can do this outside of Obsidian in Windows Explorer, but… I like staying in Obsidian 
I very much appreciate the elegance and serendipity of the tagging/linking approach but a little bit of hierarchy is needed, like some top-level folders and maybe a subfolder or two when needed to group files together visually.
Along with the menu options asked for above, it would be great if when a note is opened its containing folder is revealed in the Obsidian File Explorer.
