In the meantime we solve the previous point (hoping it is possible), I would ask another thing.
When the categories are too much or when the title is too long, the pagination is not perfect because the grid becomes broken. See the attached pic to understand what I mean.
To remove the green space and maintain the grid still perfect, I need to shorten the two text blocks (showed in the pic by arrows 1 and 2).
I thought it was very simple… I tried these scripts:

and
http://wpsnipp.com/index.php/cat/truncate-description-within-categories-admin-panel/
But they don’t work on my portfolio page 🙁
What is it the right syntax in this case?
