P: Curve adjustment graph dialog size is tiny. Please make it bigger.

feel the same on a 4k+ screen the curves layer is smaller then my handpalm. especialy when you wanna work precisely its importrant or for bad eyes. I have good eyes and i cant realy work precisely with this...

I am a digital illustrator and colorize my images with curves.
now my new wacom cintiq is almost useless with it.

I agree entirely.  The curves graph used to be larger and it truly hard to work within it now!

@Stephen Marsh, OK, let's make options as in the Layers panel.

Due to the inclusion of the histogram, I can only see this working in multiples of 256 pixels (512, 768 etc). Edit: This is obviously only true for 8 BPC images or if one isn't concerned about accurate display and an interpolated display is acceptable.

This would be helpful.

Hi - I am a relative beginner in PS. And you seem to hit on what I wanted - to have the grid larger. However my input and output are greyed out. Am I missing something to enable an input?

That’s more of a question that should be posted in the general discussion area and not really part of this specific feature request thread, but for Input and Output to be available, you have to first select a point, because Input and Output determine where that point is on the graph. For most people that happens when they click the curve to add a point to it, but you can also select the default start or end point. And most people simply drag the point where they want it, and that sets Input and Output so they don’t have to type anything.

Are they coming at it from other angles?  Point Color, for instance.  Curves are an important tool in Photoshop, but their function is the important thing, and new tools like Point Color allow us more control of that function. 

My go to approach for fine control is to lay a bunch of Color Sampler points on the image, and position the Info panel to show exactly what is happening.   Place a point on the curve using the 'little hand' icon, and adjust the Input and Output values using the cursor keys.  My mantra is 'The numbers don't lie'.   Point Color does more or less the same thing, but does it with more control.  

There is currently a pixel-level control of the  "path" adjustment but none for the "pencil" adjustment.  A larger curves dialog would make it possible to use the "pencil" adjustment with pixel-level precision as well.  There may be other ways to give more precision to the "pencil" adjustment as well...

Totally agree - make it bigger Adobe!!!!!!
