show subfolders inside of folders, at the top of notes

show subfolders inside of folders, at the top of notes

Would be great to have a folder/note structure similar to how computers & google drive/dropbox structures files.  When I open a folder in Nimbus, I'd love to see the subfolders listed.  

not a big deal on a desktop app, as the folder tree is on the side.  but on mobile, when I go to a folder, I don't see any subfolders, and frequently have to go back to see the subfolder options.

but regardless, I would love to see it on all platforms - desktop, web, & mobile.

thanks for the consideration!
