God I've wanted this forever.

So I got bored and had a go at adding this, if anyone is still interested

Nifty. It's been a while since I've looked at this. I'll try to get round to having a look at the consequences of this patch soon, and then merge and push an update.

Thanks for your work!

(PS: do you use FS2? Where? Why? :)

[bs2609]

No problem :)
I've also been looking through the code and working on fixes for a couple of other small issues I noticed.
In answer to your questions, I've mostly used FS2 while at FragSoc events, though I also occasionally use it with friends, or as a file browser.
