Need option to disable this plugin login redirect

First I want to say thank you for this awesome plugin. It works perfectly in my nav menu to show LOGIN to visitors who are not logged in and LOGOUT to those who are logged in.

However, I use Formidable Forms to manage the actual logging in and logging out. Formidable allows me to use different login redirects which is particularly useful when I put a login form in a modal in which case I would simply want to refresh the current page.

I tried to delete the contents of the Login Redirect URL on the Login or Logout Menu Item – Settings page of your plugin but it won’t allow that field to remain blank.

This plugin would be 5-stars (instead of 4.9 stars) if you could somehow allow all redirection to be handled by other plugins. Thanks again!
