How to reproduce:
go to inbox
left column: different inbox folders
Most of the participant tried to delete the folder by doing a right click instead of clicking in the "Actions"-button at the bottom of the column. Even after realizing the right klick option doesn't work and they finally did click on "Actions", they didn't always go on to the folder-"administration". --> Function hard to find, to complicated. To many steps to get there.
Presumably it's the same problem with creating folders, change folder name etc.
include the "folder-action" option in the "right click" menu. there shouldn't be another drop down menu after clicking the "folder action"button --> different points in the "main"menu:
folder-actions (=opening folder administration menu)
no further submenu:
"Right click" should provide most of the options that are available via "actions"-> "administration":
New Folder Delete Folder Rename Folder Folder Options (settings)
