A maximum height and scroll bars should be able to be implemented when editing the widget. On the summary page I use the widgets to display the most important information in the quickest method possible. This often contains list of top X servers etc. I.E Some widgets such as Nodes with Highest CPU LOAD generally are not that long. When issues arrive these can cause the widget to expand greatly pushing everything below them off of the screen. When the list starts to get long enough to have a scroll bar it would screen look at me without the need to push other information off of the screen. Note that a widget such as Nodes with Highest CPU LOAD may have multiple servers hitting 100% at once so limiting it to the top X servers is not always the best option.
