Comment 8 for bug 753652

I commited the new versions of screenlets into Dev PPA (https://launchpad.net/~screenlets-dev/+archive/ppa). Now the deskop files are installed and instead of "WhateverScreenlet.py" the title is "Whatever". Logging out and back in may be required to update the titles (it's probably because of the relative youth of Unity).

If you still want to disable all the titles, you have to make an effort yourself. Maybe something like...

Copy screenlets desktop files to your own desktop file directory:
mkdir -p ~/.local/share/applications/
cp -rv /usr/share/applications/screenlets/ /usr/share/applications/screenlets-pack-all/ /usr/share/applications/screenlets-pack-basic/ ~/.local/share/applications/

Change all the name fields for them:
find ~/.local/share/applications/screenlets/ ~/.local/share/applications/screenlets-pack-all/ ~/.local/share/applications/screenlets-pack-basic/ -name "*.desktop" | xargs sed -ri -e "s/(Name.*=)(.*)/\1 /g"

Delete the files from your home directory, if you don't like the changes made:
rm -rv ~/.local/share/applications/screenlets/ ~/.local/share/applications/screenlets-pack-all/ ~/.local/share/applications/screenlets-pack-basic/
