Is it possible to have Nautilus scripts appear in the top level of Nautilus' contextual menu, rather than in a Scripts folder?
Possible if you use Nautilus-Action.You may define your own right-click context menu items with nautilus-actions . There is no need to store scripts insde
See the full answer here:
Since most of the nautilus-scripts are basically Shell-scripts or Python-scripts (or Perl scripts) it is easy to convert them to nautilus-action scripts.
You can install most useful scripts from this ppa: ppa:dr3mro/nautilus-actions-extra
Also you can fine many useful scripts here: Nautilus-action scripts
