Good, but disappears when used with menu icons plugin

Nice and simple.

However, if you have this menu icons plugin installed;
https://wordpress.org/plugins/menu-icons/

..it doesn’t work, nor do you even see an option to select css classes.

Also, could’ve been even more simple if it worked like WP
used to work; simply a text field in the menu settings underneath
each item, where you write your css classes..

That would be more straightforward and not require to go to another
settings page to create classes.

Hope that can be changed in the future?
