Allow dashboard charts narrower than three columns

Hi all,

I'm finding the 3-column minimum for widgets on dashboards very limiting. I've got a very wide screen and even setting to 1 would make things pretty wide.

So I guess a question for datalust and anyone else that can help - why the 3-col minimum and is there a work around?

Thanks,
CJ
