Action: Close applications

[ajalkane]

Like in Applications action, but option to close applications.

This is much harder on N9 than starting applications. Requires parsing .desktop file's Exec line to get the process to try to kill. And even then it won't necessarily work. For example if the Exec line is just for launching a shell script that does something that launches the process. And even without custom shell script most applications use invoker to launch the application so that must be parsed at least.

All in all it's hairy enough that even trying to do something about this would require many requests from users to make it worthwhile to even try tackling it for common case.
