featureRequest: ordering of items in bar/dot plots

[windysky]

Hi,

It would be great if users can specify how ggbar and ggdot order the items in the plots. Currently, the default is ordering by the name of the items (pathways, etc) or Rich factor (% in genome). It would be great if we can order by Padj as well.

Thanks,
Junguk
