About 

The DepthBuddy is used to create 3D ramps based on Depth/Z or Position/PRef data, for use in the mask inputs of other nodes. It has a built in preview feature, to help you place your masks easier, and when using position data, can generate a ramp in any direction 

You can read the full documentation for the DepthBuddy here

 Features 

Generate your 3D ramp by selecting a start and end point anywhere in the preview image

Press and hold Ctrl+Alt while using the Start/End sampler on the preview image, to you place the masks quickly

The preview image doesn't affect the render result as long as you are using the resulting masks alpha channel

 Use the Offset slider to finetune the overall position of your ramp, without changing the distance between the start/end points

 The Buddy System 

This is a suite of tools I've been working on, which is designed to help compositors of all skill levels accomplish fundamental tasks, quickly and intuitively

If you'd like to learn about the other Buddy System tools you can find them here, and feel free to reach out if there are any issues, or if you have ideas to improve them!
