I really like to customize my admin experience, and installed this plugin to distinguish the icons when other plugin developers default to things like “post icon.” Seems to lack support but that is how it goes with open source plugins. Many thanks when it works 🙂

Hi, I am a beginner and have no idea about CSS coding and wondered if someone can help with providing the CSS code to replace the footer color of the website with an image, thanks.

This plugin did *exactly* what I wanted. A plugin had dropped some ad stuff into the Publish box, but it had a good CSS class, so I just hid it. I really like that the text field for holding the CSS is intelligent and does things like auto include closing brackets, code coloring, etc.

If you get fed up of all the nag screens from themes and plugins nagging you to “Go Pro” etc, then this is a great plugin for adding css to hide them all. Really easy to use.

Fantastic plugin, perfect for editing your admin panel. Not needing to deal with the hassle of php. files is great. I just hope this plugin gets an update for wordpress 5.7 soon as some things seem to not be working as they used to. Regardless, thank you so much Scott for your amazing work!
