With this editing mode you edit the things in your map. Drag the things to move them and snap them to the grid. Hold Shift to disable snapping to the grid. You can use the Things Filter in the toolbar to show only things with specific properties (such as multiplayer things or things that only appear at a hard skill level).
The things editing mode is one of the classic (2D) editing modes.
