Thanks for reply. I did try the new behavior and it seriously ruins my workflow, but I do understand why this was patched and approved. Unfortunately I don't have the skills to help with patches, but I would be happy to reward a developer with time/skills that would be willing to bring back the old (mirroring) behavior as an option. Does any mechanism exist to put a bounty on a wanted feature?

What would be the level of effort to make the split view behavior change optional. This change forced me to downgrade to version 18 since it seriously broke my workflow.
