Plasma 5 file transfer notification windows

[jaegermeister]

Hello,

while in KDE4 it was possible to choose which notifications to show in system tray/panel and, with regards to file transfer ones, it was possible to show them as small windows that appared in the desktop till the end of the transfer, instead of being shown in the tray (which I am not comfortable with); in Plasma 5 this option seems disappeared or, if moved, I cannot guess where it is.

Any clues?
