I like the functionality here, but am not crazy about the amount of vertical space it takes up for a not-that-popular action.

If we could somehow move it to the bottom, or find some additional functionality to add to this new toolbar, I think it would work better. I'm going to take some time to think on it.

can be done the same for Headers?

Thanks for this, and sorry it sat so long.

The code is good. I just could not find a home for the control I was happy with, and a permanent header row above every pair editor is a lot of standing weight for something people do rarely. The request that kicked this off was an import that enabled over a hundred params, so I am fixing that instead: #486 gives OpenAPI a native importer that leaves optional params disabled.

Closing this one, but I appreciate the work.
