Move applications among activities in KDE 4.10.1 [solved]

[mani001]

is that not possible anymore?

In KDE 4.9.5 there was an option in the upper-left menu of every window (or, equivalently, clicking with the right button on the corresponding application in the task bar), but I cannot find that option anymore... I never install kde-meta, so I'm not sure if there is a relevant package missing (although I can create new activities, tell KDE to always open an application in the same activity and things like that).

Cheers!!

Just in case someone comes across the same problem...it seems powerdevil is a requirement for the activities thing to work properlyl (not very intuitive). Adding solved...
