Ack - sorry for the late reply, didn't get the notification for the last couple of posts (or most probably simply missed it ).

Sadly, no. That would require to create an essential system file on the fly, making the app more risky to use, and I decided against this. By now I have to admit that I'm pretty much wavering (it has been requested a couple of times already), but at least in the next couple of versions I'll not include this functionality. Sorry...

I just had an idea on how to solve this...
I'll give it a try after work, but I don't see any reason why this shouldn't work...
I feel pretty stupid I didn't think of it earlier, especially since the vital hint already was given in one of the bug reports...
