Shift Render Slot automatically shifts the active render slot in the UV/Image Editor during rendering. This prevents new renders from overwriting previous ones, allowing you to easily compare test renders without having to manually change slots before each shot.

You can configure the tool to trigger the slot shift before, after, upon completion, or upon cancellation of a render job. It also includes shortcuts for navigating slots directly from the UV/Image Editor and allows you to set the shift direction to increase or decrease. The tool's state is linked to the scene and saves with your project file so your configuration remains intact between sessions.
