It closely follows Facepunch's Sandbox gamemode, with additions to make it more extendable by other modules (adding events, publicizing UI globals, etc), while staying unopinionated/light. This module is primarily aiming to become a "Gmod 2", replicating the functionality found in Gmod's Sandbox gamemode (with improvements).

• Constraint tool: an omni-tool with all your classic Gmod constraints (weld/axis/rope/elastic/slider/ballsocket)
• Duplicator tool
• Material tool
• Toolgun model (wip)
• Undo/Redo System
• DynShapes spawnmenu: like PHX, but dynamic, fully customizable sizes using procedural meshes. Rectangles, cylinders, spheres, gears!
• UI tool panels, including ModelSelector with extendable .spawnlist's

• IStopUsing entity interface
• Many new events (aiming to reproduce many of Gmod 1's), including "entity.spawned" event, "undo.add" event

• Wirebox, playable as Sandbox With Wirebox
• Stargate
• Sbox Tool Auto, which is a simple example addon recreating gmod_tool_auto behaviour
• Undo Manager (outdated, will probably just add to the base gamemode) now part of SandboxPlus
• AdminEssentials, non-gamemode-specific, non-open-source.
• Napkins-Chat (outdated)

• Wirelib
• NData (ClientRPC substitute)
• Permission framework
