For those who stray away from using KDE for awhile. It’s most likely a bad idea. cause once a person knows the super does the resize and moving with the mouse clicks there is no need. Only to throw it out there because I remember using my arm laptop which doesnt actually have a super key. And now again after not using kde for a bit I forgot about the super key. But no more. There is no way I will forget the super key now . I was fiddling in the kwin menu preferences wondering why the mouse clicks weren’t able to be program within. and then it struck me quickly . the super key covers it.
I do not believe that sending a notification about features that may be of interest is currently something that KDE is planning on doing for the meantime.
Thanks for your suggestion!
