I’ve taken quite an amount of time to test this out and I’ve concluded it just must be beyond my ability. I have the hooks provided to me by the plugin’s developer but I can’t figure out where to place them and how to implement it. I’ve found the location shown in the codex but I don’t understand how to simply add something to the admin bar without changing the menus. I just want to add this button to the bar if no one is logged on.

On a side note, is there a way to make the admin bar thicker? I’d like it to be somewhat more substantial.
