   There is a clash between _global_/_environment_-like solution and _local_ solution. Only `DataEditorSupport` knows what it wants exactly to do when a file is changed. That's the _local_ knowledge. I am afraid you'd need many pluggable strategies for each individual case.
   
   The best way to implement the _global_/_environment_ solution is to replace current implementation of FileSystem (e.g. `masterfs`) with another one that would be tighter integrated with VSCode workspaces concept.
   
   > strategy for files/dobjs
   
   The important difference between `FileObject` and `DataObject` in this case is __identity__. When a `FileObject` is moved or renamed, it changes identity. Moving or renaming `DataObject` keeps the identity. To match VSCode/NetBeans concepts when renaming an open and modified editor, it would be desirable to keep `DataObject`'s identity - that's not the case right now.
