Ah I didn't think of having a set of options - that's a good idea. Indeed I'll keep playing around with it and let you know if I have any feedback, though it's already pretty nifty! I'll take the new changes for a spin probably tomorrow. Nice work Andy!

I don't think it would work well with the current framework but in a plugin like this, having a command you could pass to do the estimation would be cool. For the above example, to estimate the size off the top of my head I would have done "du -sc /var/lib/ldap | tail -n1 | awk {'print $1'}" so having a callable mechanism for that would be pretty neat.
