As different profiles can be created and used to refelect a changed behaviour in different Programs (drawing / browsing / etc) a way to automatically switch between profiles would be great, KWin has the possibility to add rules for different windows based on their window title. We should check if we could add support to the wacom kded to get notified when the active window changes and if we need to change the profile for the current tablet. The KCM should also extended to allow setting program/window rules where the profile will be used.
Some implementation hints <mgraesslin> if it lives in kde-workspace the easiest is of course to link libtaskmanager <mgraesslin> if it's outside kde-workspace you want KWindowSystem
