Restore Column View

I recently upgraded to SourceTree 1.9.1. It no longer has the column view of the working copy. Everything is flat. Please restore the option to have the column view of the working copy. Sometimes, it is much easier to add files for commits, by adding the enclosing folder, instead of having to select via checkboxes. It can be very confusing to have to look through a long list of checkboxes, if a lot of items need to be added at once.
