As a roblox developer, it is currently too hard to edit the way Images are expressed on the screen. For instance, it’s impossible to reduce the saturation (Make black and white) on an image without importing a new image and making the client load a new asset of the image black & white.
I’d like to see some sort of image modifiers in roblox. Essentially, a color correction that only works on one image. Perhaps it could be a property in the Image tab? Image -> Blur & Saturation. I think it would be very useful to have these options because it would allow tweening between saturated and unsaturated, blurred and unblurred, and it would be very useful for making buttons 
For now these are the ideas I have in mind, but I’ll grow this list as I come up with more:
- Saturation
- Blur
- Pixelation
- Color Hue
- Gradients
