closes #944

mahkoh · 2026-05-18T09:01:48Z

Please make this a tristate Never, Always, OnRemove where OnRemove only takes effect when the second-to-last child of a container is removed.

This requires adding a non_exhaustive enum to jay-config and a corresponding enum in Jay proper.

~~I think this should also be under the [theme] table in the toml config.~~

You also have to add a corresponding setting in the look-and-feel pane in the control center.

Is the difference between Always and OnRemove that OnRemove lets you manually nest a single child deep in a tree? Always should be closest to how i3 behaves.

Yes.

+        && reuse

+    }


This can be a one-line change.

            show_bar: show_bar.despan(),
            split_reuses_container: split_reuses_container.despan(),
            show_titles: show_titles.despan(),
+            flatten_tree: flatten_tree.as_ref().map(|v| parse_flatten_tree(v)),


Use the same style as the other settings above.
