Really like the editor, but one thing that has been bothering me is the size of the font of the resource tree.  It seems that regardless of what I change in the CSS file, I can't affect the size of the resource tree folder names, and individual elements below. Is this intentional, or am I missing something? 

Thanks!

You want to override size in the item, like

.treeview .dir > .header, .treeview .item { font-size: 15px }

wow, thank you so much for your quick response!
