editNodes

v1.1 - Able to change or add expression on keyframe animated knobs.

Select two or more nodes and run script. A panel opens and shows all shared knobs (e.g. reformat with a tranform node will show 'filter', plus more. Same node types will show all knobs in node). You can either copy/paste or link knobs separately. The change is applied when the copy or link button, pointing to specific knob, is pressed. Not all types of knobs are included in the tool, but the most frequently used ones are hopefully there. 

Copy file to .nuke directory

A suggested menu.py entry:

import editNodes

nodeMenu = nuke.menu('Nuke').findItem('Edit')

nodeMenu.addCommand('Edit nodes', 'editNodes.editNodes()', 'ctrl+e')
