If this fantastic plugin has input-min, input-max, output-min and output-max of every channel?

[MarioMey]

I was looking for a RGB levels plugin and I found this. It was a bit hard to me to understand what it does... until I get the functionality: it changes input min and max of every channel. But, unfortunally, I was needing to change output min and max.

Can this plugin be upgraded to have 6 more sliders?

RED input-min
RED input-max
RED output-min
RED output-max
GREEN input-min
GREEN input-max
GREEN output-min
GREEN output-max
BLUE input-min
BLUE input-max
BLUE output-min
BLUE output-max

As Levels in GIMP:

I want to make the TikTok disco effect as here: https://www.youtube.com/watch?v=UrnOb_YeNEA (I don't like TikTok! But I want to use this filter because of my job: I make spectacles in children birthdays). I would change its color values dinamically using PureData, obs-websocket-py and obs-websocket, of course.

I program in Python... but C and shaders are far from my knowledge.

Thanks for this plugin.
