The HUDFramework mod adds additional functionality to Sim Settlements. It allows the user to view settlement needs without having to open the Pip-Boy, or open the workshop menus. With HUDFramework installed, settlement needs will be displayed on the left side of the screen when inside of or near a settlement. The shown needs are not limited to those in the vanilla game, and also include those added or adjusted by Sim Settlments, including power.
