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

I've been waiting twenty years for a larger Curves graph. 

Same here! There should be scalability and flexibility in the Curve Adjustment tool.

been how mnay years and no sign of change 😞

So, Adobe,

6 years at your job for this and 11 for Lightroom Classic. What the actual [blank] is up. It's inconceviably irrational for you to drop a massive curve panel on iPad then screw your entire core user base with zero commitment to Photoshop and Lightroom core utilities, instead chasing all the AI 'fun tools' that don't truly provide professional solutions.

Pay attention to your core offering. I hate this company in it's current state and hope whatever acquistion comes next gets barred as you aren't honorable enough to be conjoined to the next victim.

Good idea. Voted.

We're quickly approaching 2025 and no sign of these tiny curves windows getting any bigger 😞

It would be great if this could be fixed. Some people say. Each interface in Photoshop works according to the OS magnification setting
Then why can I expand the Color tab as much as I want regardless of the resolution of 4k, 2k, and fhd?
This is reported on the Ideas tab, but it seems to be actually a bug. I want to see the curve adjustment widely even though I use the wide working environment of 4k. And people who draw are using color tabs so well.
However, because the adjustment tab is not resized as expected due to a bug, you need to semi-force resolution or scale.

Is there any room for improvement on this? I personally have very poor eyesight.

Regardless of window UI scaling, certain tabs in Photoshop have limitations in increasing the size of the tabs. I can't really see it.

The size of the tab changes to fit the size of the tab, but it stays fixed beyond a certain point. But people like me who have poor eyesight often ask for something bigger and clearer.

I can't say it's necessary. Because I've been working in a state that I can't see well for over 10 years. But there are many people who have eye problems like me who are experiencing Photoshop. For them, this small improvement would be very helpful.

Sure, massive curves window on Lightroom for iPad, but anyway to do this in the core Photoshop program? This drives me insane. Why [removed by moderator] isn't this responsive in 2022. Did I miss something?

I'd like to suggest that the curves histogram in the Properties panel be made responsive.  This way, if you expand the size of the panel, the histogram would grow proportionately, and allow for easier mouse use when fine tuning of points on the curves.
