Add Distortion correction slider to Transform Panel. It would be useful when doing lens corrections. Think about it, please.
I mean when I'm doing a correction to my wide angle lens I'm using transform panel (vertical transform etc.) but with doing that I need to correct distortion (when I do vertical transform of wide angle lens distortion is more visible) - I need to go up to lens correction panel - do the distortion correction and sometimes need to go down again to transform panel. I think It would by useful to have distortion slider in transform panel too (I don't mean to delete it from lens correction panel - only option to have it in transform panel too).
