Can you please do something about the size of the nodes in Bloom; now there are only 4-5 sizes you have to manually set up. What we need is the automatic assignment of the sizes of the nodes based on centrality metrics values for them- to get the real picture of the prominence of nodes in the network. Thanks

Sometime nodes contain link to local picture or to webservices which generates pictures (e.g. node name = person + pic or node name = chemical structure). it would be good to have a "mouse on" feature which allows user to let this picture pop up while on the node or with a simple click on it.
