Small feature request question here, and I'm interested to see if it's only me that would ever find benefit from this function.

I've recieved an email from a company confirming a delivery, this company sends out attached to that email, an ics file containing the details. I can save that attachment, the go to preferences and import/export, and browse to the file, and import the .ics to the calendar and then Boom! the appointment for the delivery now appears in my calendar - which is nice.

It'd be nicer though if I could click on the attachment while reading the email and have the appointment added to the calendar, rather than taking the file out and putting it back in.

Has anyone else ever wanted this, would it be useful to anyone, or am I just being lazy ?
