The implementation is almost identical to the one done by Martin; details available at : http://www.sugarlabs.org/~tch/journal2.mpeg
The only differences are ::
- More copy-to options :: Clipboard, Documents (in addition to mounted drives).
- When entries are copied to another location, both - the sources and the destinations - are de-selected automatically, without the user explicitly have to de-select them all manually.
- There has been a progress bar added for batch-operations.
