This is your very personal wish, and it may come as an option.
I come from Total Commander and always use double pane in TC and XY,
but I never miss a double tree.
I have it in TC since many versions, but never use it.
Most of the time, there is no need for any tree at all, and I switch it off.
There are tools like Everything, Favorites and tabs for fast going to certain locations
in both file managers.
