Hi,

 

The problem is there since a few a versions:

 

- First mark some items

- Then select some other item with some subitems, and keep the hierarchy collapsed.

- click on the option "add marked items as children"

- the marked items are put under the item ("add marked items as children") but 1- they don't show (the new parent remains collapsed), 2- and the focus is moved under the parent, but invisible/hidden, unless one expands the hierarchy ore repeatedly click on down or up arrow to bring the focus to the parent item.

 

Thanks!
