The portfolio categories are generated from a cycle so it is impossible to add different icons on top of them. So you can only edit the includes\view\portfolio\loop-grid.php file to add the same icon (gets generated in the cycle together with categories) or add different ones with css.
Sorry but this is a customization not included in theme support so this is all i can help.
-What do you mean by center categories? Show them in a drop down or just diminish the width? The first option requires code editing, while the second you can do it with some css.
Thank you! I suppose I’m trying to diminish the width? The categories at top for the portfolio aren’t horizontally center-aligned with the images of the portfolio grid, and I’d like to do that.
