No CAPTCHA reCAPTCHA

EDIT: The problems described below have been improved by Collins Agbonghama. I haven't verified, but I'm going to upgrade from 4-stars to a 5-star review for taking care of the issues I faced a few months ago :)

A couple issues with this plugin, all of which can easily be fixed (and let me know if they do get fixed, I will happily add that star back into it!)

First, I'm using a custom theme with very few modifications, and no modifications to the backend. So these would likely affect a vanilla WordPress install.

Issue #1) The settings page for this plugin is a massive menu item. It's the only link in the menu that takes up two lines. And it's a page you only need to use once. The link should be moved to the Settings menu, as a submenu item.

Issue #2) The ReCaptcha widget is clearly lacking some bottom margin on the login screen. It's almost touching the button to sign in. This issue can easily fixed with CSS, but for some reason it was neglected.

Issue #3) The default verbiage for the recaptcha error can only be described as poor English. Thankfully you can change it, but you are going to want to change it on every site. The default is currently "ERROR: Please retry CAPTCHA". It is important to note that the "No Captcha" ReCAPTCHA is not a captcha. That's the whole point. Captchas involve letters. The error should say something like:

"ERROR: Please retry ReCAPTCHA" - at the very least, refer to the brand as this is NOT a regular captcha field.

"ERROR: Please confirm you are not a robot"

"ERROR: Please check the box below to prove you are a human"

etc.

Everything else looks good. These are quite nit-picky "issues" too. So unless these really bother you, this is a worthwhile plugin.

Hopefully these issues can be fixed and this becomes a stellar plugin! Thanks!

Works, but needs improvement (Improved 9/18/2017)
