Magic Lamp Effect is too fast, option should be given to change animation speed.

[AcidRain9]

The magic lamp effect is too fast, it should be slowed down a little bit, or an option should be present for the user to choose animation speed.

SideNote:
Kwin has another similar effect "Yet another Magic Lamp"
Maybe the default Magic Lamp can be replaced by "Yet another Magic Lamp with Shape set to Bezier" I think it's better than "Magic Lamp"

Finetuning animation speed can be done via KDE's systemsettings (since it's a KWin animation).

Such functionality may not be developed for the time being; you can modify it yourself
