RGB Channel View Tool

I know that nuke has the option to press R, G, and B to see the RGB channels individually but I wanted an easier way to see the three channels as sometimes I forget to change the channel im viewing and wonder why changing values isn't changing anything.

this is a very simple tool that just separates the RGB channels of the input and displays the contribution of each channel in the same way as the shortcut keys do.

I made this tool mainly just to help me, as I find it easier to adjust all 3 channels at the same time if I can see them at the same time as I don't have to worry about forgetting to switch what channel I am viewing.
