The node configuration view is a window that is shown after right-clicking on a node and choosing configure.
Nodes normally have 2 main sections: View and Buttons - and sometimes a third, message area which can appear on top.
The message at the top of the window has a menu which can be used to choose how often it should be shown. Access it by right-clicking on a message that is shown and choose an appropriate setting, for example, show always or hide always. The setting can also be set globally, for all nodes using the the area. See Preferences -> Node Configuration -> Show message area.
The main node view, it is specific to each node and might be generated from the nodes parameters or a custom written GUI.
