Thank you very much for this quick and long response!
Unfortunately I’m not really skilled with PHP. But I’m sure that the result I’d like to see could come by changing in this PHP file the place of these two icons (the CSS file is perfectly balanced and only minor changes can come this way). By the way, I have tried the 2 as you told, but the result was not convincing.
I have prepapred a demo image if you like to see how it would look like (I have put the 2 icons in a confortable place while using the image editor: they could be elsewhere).
The demo imag is here (www.fedescol.org/images/EFLP+Demo.png), and there you can find a page where I am deploying your great component: http://www.fedescol.org/partage/tous-les-documents
