Choose your screen options before installing this plugin!

I installed this plugin to add word count to the admin lists of posts and plugins.
I am using Yoast SEO, which adds columns for some SEO features (links, SEO score, readability score).
Normally I configure the admin list by clicking Screen Options on the admin list. However, when I installed this plugin I was no longer able to open the Screen Options, that link was disabled. The plugin had added a column for Word Count but apparently blocked further choice of Screen Options.
This may be a glitch in the plugin. However, it’s more likely a problem caused because Yoast is already trying to add columns to Screen Options, therefore this plugin collides with it.
In any case, you’re advised to set up your desired Screen Options before you activate this plugin, because otherwise you may not be able to choose them any more.
I also agree with the other reviewer who advised adding Word Count to Drafts as well.
