I read here about changing the icons and it kind of work. But I realize the icons we have are stacked icons and this seems to not be achievable in the additional css.
I see you are right, I understand. I apologize for my confusion.
On the other hand I saw in gist the php files
are these the ones defining those icon in the first place?
I want to use fontawesome syntax to combine several icons together and would like to override that template part. I need to confirm if these are the PHP that need to be overridden.
