Node monitor flickers

Dear KNIMErs,

Just a heads-up: the Node Monitor view flickers for rapidly executing loops, making the live variable display mostly unreadable. I think it's because the node state is also diplayed, and it alternates rapidly for all nodes in the flow (IDLE/EXECUTING/EXECUTED).

Could this become an optional field to show or update, so that the monitor's updates are limited to when a variable or an output changes instead? Node states aren't all that interesting to watch in this view anyhow...
