Sadly my app doesn't look too good with the new sidebar style and currently I don't have the time to redesign it. (That will come later).
When using Xcode 26 is there a way to keep the sidebar behavior but use the old Sequoia look?
I initialize my sidebar splitview item with NSSplitViewItem(sidebarWithViewController: - when I switch to a different inititalizer (contentlist, inspector) it looks OK but the sidebar behavior (tracking toolbar item) is gone and the toolbar looks broken.
Any other way to keep the old style besides not upgrading to Xcode 26?
(The friendly integrated AI hallucinated some BS and then somehow applied those changes to my code ... luckily I had no pending code changes and could just revert via git).
