This plug-in will remove/hide pro features so the interface will be a bit cleaner. 
Tested with Elementor 3.35.0.
Note: if you already use a child theme with an admin style I recommend looking at the plugin source and just add those to your admin CSS instead of adding the plugin!
It will clean up the following parts: 
* remove the “upgrade” button from the main Elementor menu 
* hides the upgrade features from the “home” feature list 
* hides the Youtube iframe and banner image from the editor – quick settings page 
* hides the upgrade button from the editor submenu 
* hides all pro widgets in the Elementor Editor panel 
* hides the promotion messages in the Elementor Editor 
* hides the upgrade banner from the Hello menu
If you use <a href="https://be.elementor.com/visit/?bta=207645&brand=elementor" rel="nofollow ugc">Elementor Pro</a> it will keep the Pro features visible.
