Quick Tools is a utility addon that adds a panel to the 3D Viewport sidebar with various selection and modification operators. It provides tools for visually identifying instanced objects and objects with mirror or array modifiers by assigning random viewport colors. Additional selection tools allow users to find objects with non-uniform scale, select meshes with un-seamed sharp edges, and select objects that share specific modifiers.

The addon includes bulk modifier management features for adding, removing, or copying specific modifiers across multiple selected objects, with dedicated tabs for Mirror, Triangulate, Shrinkwrap, and Weighted Normal modifiers. It also features utilities for copying transforms to multiple objects, stripping materials from selections, updating mesh data names to match object names, and shifting UVs for mirrored objects to prevent baking artifacts.
