I think your question has nothing to do with the documentation. On a free to download component you can check yourself if the option is or not available at the extension backend!
Thanks :) We've just updated and in the style2 you can now set the icons size to 32, 48 or 64 pixels.
Best of all, support is outstanding. Again, being a newbie, I am going to have questions and some possible tweaks. I always had my question answered or a solution developed the same day.
Keep up the good work.
