D&D Beyond DM-Screen & Spell List Manager is a customizable DM screen for D&D Beyond campaigns and a spell list manager. This program is available on the Chrome platform and is developed by silas. It falls under the category of Browsers and the subcategory of Add-ons & Tools.

The DM screen feature allows users to decide which information of the players should be displayed, giving them control over the campaign. The extension's settings can be easily customized by opening a character under DNDBeyond.

The Spell List Manager is particularly helpful for classes that can change their spells on a daily basis. With this plugin, users can save their current prepared spells (excluding cantrips) and easily select them again on a later day. This feature allows for better organization and planning during gameplay.

Additionally, the program offers a Defense Roll feature which provides an alternative way to shape monster attacks. By involving the player in rolling to escape the monster's attack, it enhances roleplay and makes the player the focus of the narrative.
