Improve miniatures in LibreOffice

How can I see my icon files better in LibreOffice?...

There is just a snag with some of my files, and I found a solution to fix that.

You only have to install this PPA in your pc.

sudo add-apt-repository ppa:atareao/thumbnailers
sudo apt-get update
sudo apt-get install lothumbnailer

Then of this, clean cache with:

rm ~/.cache/thumbnails/fail/gnome-thumbnail-factory/*
rm ~/.cache/thumbnails/large/*
rm ~/.cache/thumbnails/normal/*
killall nautilus



 That's all to look like that.
