Hi
I have this same request so I hope you don’t mind me commenting here.
I think adding code directly to the theme is preferable to installing the insert headers n footers plugin. Reason being, that plugin has not been updated for the past 4 months and not tested with wordpress latest versions. Lesser plugins is always a good idea.
It’s true that this code will be lost when we change the theme but that’s a future problem which may or may not even happen if we stick to this theme for the foreseeable future.
Will be great if you guys could consider letting us add the code directly to the theme somewhere?
