@toran #PlasmaGear is one of the three major components that KDE release separately. There's #Plasma which is the desktop env + window manager; there's Frameworks which are the utility libraries; and then there's #PlasmaGear which contains the KDE apps which are not released standalone, like Elisa, Glenview, most games etc.

#Kasts was part of Mobile Gear which is a much smaller set of packages intended mainly (but not solely) for use on Linux phones.

For the next release #Kasts will move from #KDE #PlasmaMobile Gear to regular #PlasmaGear

There are already a few new features queueing up for that next release: support for a system tray icon, search functionality and setting custom playback speeds.
