Astute Graphics plugin panels use the color coding to help to distinguish their panels. They use 4 color / functionality categories, and use these to color narrow strips at the top of each panel. These does not cause mayhem but helps to locate and distinguish the panels.

Unavailable menu characters are too dark to be distinguished, so I want you to be able to change the colors yourself.

For all adobe products: there are many many panels all the same gray color background. If the panels had colors, one could work faster. I could always use blue as my Type-panel background for all my adobe applications. When I need to work with type, I could find the type panel more quickly if it was blue instead of one of the 10 gray panels on the monitor.

Would let designers work faster and more efficiently (time is money)

With Retina Displays and multiple 4K and 5K screens, when we take advantage of the additional real estate, we can't enjoy using our apps, because we can't see text, or icons or anything. Windows has the ability to change their text for high-resolution screens - Macs should have the same option!

Help! I love that Photoshop gives us the tools to change the way our toolbars look by highlighting the text in the columns with beautiful colors to the ones we use the most. I have yet to find this in Illustrator and I'm pouting; my memory depends on color coded hints... because that's what they taught me in kindergarten.
I added an image with screen shots for my artsy comrades as we are all visual beings. I'm going to wait in my happy place until I hear from you. Thank you in advance.

Absolutely. It would be sooo helpful to be able to increase the size of menus and items.

If I'm right Adobe is working on a scalable interface project for Windows, and I wonder why. this can't be taken on for 4k and 5k Macs. It would be great to use Illustrator to work in the app at high screen resolutions. But as you know the interface does not scale, so if you are in a higher resolution mode the menus and other parts of the interface are very tiny.

I've been told this could be an issue that Apple needs to resolve at the operating system level. I'd love to see Apple and Adobe work this out together.

Allow the user to adjust the tool pointers. The accuracy remains the same, but the pointer could be adjusted for personal comfort.

As we can do it in PS and ID: menu customisation (colors).
Would be great.
