The code explorer can be seen as the map in a master-detail view. Then 
the file list (editor tabs) also could be added to the code explorer.

Every (future) editor window should have its own code explorer.

BTW, the memory consumption should be a fraction of your estimate, 
because every node only contains the identifier name and a file 
reference and position.
