New button in Adjustment window for Photoshop

I understand that this is a little different from what the @Alex Millman  wants, but it is worth mentioning the wonderful panel from @Davide_Barranca12040269, Floating Adjustments, which allows you to edit adjustment layers in a modal window

Alex, I'd offer a script to create a new curves adjustment layer, then you can assign the old modal keyboard shortcut of CMD + M to the script (same for the other legacy adjustments). The best of both worlds! I get it, I too first used Photoshop before it had layers and have chosen to adapt rather than fight against various keyboard shortcut changes over the years.

Thanks Stephen. I work a lot with adjustment, I like shortcuts for it, like Comand+M, +L, +U, Adjustment Layer palette is smaller, yes I can make it bigger, but this not solve problem, I discover PS in 1992 it was PS 2.5., Yes I'm archaic. But those inovation in PS not help me in a lot of cases. sometimes when I work like a machine I need this button in Adjustment dialog is usefull, when I want this. I don'tthink is a big deal make this button. And I think o lot of production/prepress peoples thanks for this.

Hi Jeff, I don't want save as preset, I want save as an Adjustment Layer from Curves or other adjustment dialogs.

By @Alex Millman

This topic is an idea/feature request. End users can only do so much with the tools on offer. The preset is the "standard" approach, outside of scripting.

Of course, the simple answer would be to just work with an adjustment layer from the beginning, then delete it if you don't wish to use it. Your choice of modal adjustment first complicates things, necessitating either preset or script workarounds to try to offer something similar to your feature request.

Hi Jeff, I don't want save as preset, I want save as an Adjustment Layer from Curves or other adjustment dialogs.

If I understood you correctly, then this script can solve the problem: after activation, it remembers the result of each application of curves or levels. If you hold down the Shift key when creating the corresponding adjustment layer, it automatically substitutes the last saved settings. Without pressing Shift, the adjustment layer will be created with the default settings.

From within the Curves or other adjustment dialogs you can save a preset, which can then be reloaded in either adjustment or adjustment layer dialogs.

The advantage in using adjustment layers over Image>Adjustments is you can change the settings without permanently altering the image.
