Move Folder
You can move a folder to a new place in the left sidebar structure.
To do this, you must first select the structure you want to move:
Right click (or '...' menu) : Select to Move
Then you need to select the target-folder under which you want to place this structure:
Right click (or '...' menu) : Move here
Your moved folder will appear in its new location and the structures will be updated with the actual hierarchy.
