Favicon in Control Panel I'd like to add my site's favicon to the admin part of the site.

I tried to do this using the "Site icon" option under general settings. That adds the icon to the sidebar but not as a favicon.

The only way I've found that works so far is by editing the CP's base layout template and adding it there, but that's obviously a bad idea, as that will get overwritten on update.

Anyone found another way to fix this?
If you have a favicon.ico at the base level of your public site I think that should do it. All I can tell you is that this is what works for me.
