First, thank you for this very useful plugin.
I found a bug with the hightlighting and custom post type.
When I edit a custom post, it's never a good menu that is highlighted on the admin menu.
This bug comes from file "menu-highlight-fix.js" with how to define if the link is the Current "Bestmatch" or not.
In my case, the script detects that it is not the best link .... but it is!
It really spoils the navgation a content type to the other and causes a lot of confusion for the user.
how to fix it?
Thanks for your answer.
