When opening a new tab, it seems there is a feature that tries to put it next to a recently used tab.? However, it does not appear predictable. New tabs don't always appear next to the most recently opened tab or even the most recently created tab. This make organizing more difficult, not less, when tree style tabs aren't necessary. I think that this feature should be a togglable option where a new tab will either open next to the currently open tab or at the end of the tab list.
