The flow-chart image does look cool. 
For my workflow, I divide the projects into folders. For example:
Month & Year of Project (Super Parent Folder) -> Review of Book xyz (Parent Folder) -> Individual Reviews of Chapters (md files).
Now when I am working with “Chapter 2 Review.md”, it would be great if the file explorer automatically shows the content of the folder, in which the current file is situated. If I go to another file in another folder using breadcrumbs, the file explorer view should shift to that folder.
At the moment, I am using windows explorer to view the folder and filename, after interrupting my work flow -> then get back into obsidian again after locating the file -> go to search (or breadcrumbs) and locate the file I want. The current view of the file explorer is basically of no use to me.
I am eagerly awaiting the feature that would make file explorer display the contents of the currently focussed file.
