ActionScript source path view: show/select currently active file in editor

If a file is opened (not by click on file in _ActionScript source path view_) from source-path folder, there is no way to quickly look into parent folder files. Expected is to see file selected in _ActionScript source path view_.
Also, if file is opened by click in _ActionScript source path view_, then focus is changed to another file in editor, selected file in _ActionScript source path view_ should change also.
