I would like to be able to vary sizes and information shown on each widget on a per-widget basis.
Right now I get 3 sizes, and they ALL have to be that way. This is suboptimal to say the least for a dashboard type tool. I would be able to specify that this widget only shows gauge-style displays. Another one that shows charts only. It would be wonderful as well to say that this widget takes up a whole row, or the full height but only one column wide, etc.
