Improvements in the KDE 4 version:

- Input can be copied to all other sessions or only a subset of sessions,
  selection is via a filter-able list which appears when 'Copy Input To...' is clicked.
- Input can be sent from a tab in one window to a tab in another window
  (all sessions in all windows are displayed in the filter window)
