Nested sorting

In 2.5, VIP had a pane that supported nested sorting(sort by priority, then project, then time left, etc. This was done by dragging column headers into that special pane.

With 2.7.1 I seem unable to locate that feature, or any replacement feature. Has it indeed been dropped, or am I just blindfolded and fail to activate it somehow?

You just missed it.

Please do the following:

1. Right click on any column header.
2. Check on "Group by box" option.

Thanks, sorted.
