Brief Summary
Nested vertical tabs allow selecting 'Close Tabs Below' in a top level tab's context menu, however a nested/non-root tab's context menu does not offer that option. It would be nice to be able to close all tabs below any other tab regardless of nesting.
Details:
Currently it is impossible to use the bottom nested tab in a tree as the cutoff point and have Orion close all tabs below that, or any other point in the tab tree that isn't a top level tab. It would be nice if this limitation was lifted since the name 'Close Tabs Below' doesn't suggest any connection to nesting and should be able to be initiated from any arbitrary tab.
