For adding chromatic aberation and lens bluring to an image. Inspired by Sebastian Schütt 's   latest youtube video for RGB matte merging , LW_Merge_Aberation uses the incoming alpha from the FG input to essentially perform a merge over operation for each channel seperatly, enabling you to get better results.

A node designed for creating shadow plates from footage. It uses the classic keyer and grade stack method but simplified using plus and minus buttons, dynamlcally stacking nodes internally. Alternatively you can also create a plate with no shadows at all by inverting the key and pushing the multiplyer above 1.

Exponentially blurs an image using multiple blurs. Can increase and decrease the amount of blurs used using the plus and minus buttons as well as the integer knob.

A simple script that asks the user how many frames are in the handles and sets the viewer in and out.

A script that adds a user button which calculates the new format size of the input by dividing bbox by format. This was how I calculated the Lens Distortion Format before Foundry added this feature to the LD node. I think this is a useful and bug free technique to have when dealing with distortions and overscan in general.
