Hello,
I did not install it. I just went through the folders and saw that the images in "/images/buttons/compose_pas.png" look like the same as those available in the original distribution. So I thought the other pages may also be the same. But I see that the "images/buttons" folder is different. My mistake. I will install and see.
Thanks for sharing a text theme. Many of my users complain about the lack of clarity in the existing default icon set. Good work.
Regards.
