I have to admit that I was hesitant when gutenberg rolled out. But I have really grown to love WordPress.
But what do I want to see built in? That’s an easy answer
Plugin Performance Profiler
It’s a plugin that tells you how many resources each of the other plugins uses. This plugin is commonly known as P3 and it was my favorite plugin for many years. Unfortunately, this plugin hasn’t been updated in 3 or 4 years, if I remember correctly. It is dangerous to ever run plugins that are that old, and WordPress has changed a lot in the last 3 or 4 years. I haven’t had a ton of success with this plugin recently but I do get it to work sometimes.
