All Nodes with GIs are shown by default unless made invisible by some other action. This option hides all nodes of a given type (GI) regardless of the depth of the tree and the content. At present this is customised in start-up files (e.g. dtd/local.tcl and routine GI::setHidden) but I plan to make this customisable after a DTD has been read in (maybe through a 'Settings' page for any GI).
NOTE: For an unfamiliar DTD it is often useful to explore it without "Hide Nodes" first (using a variety of Depth settings in the TOC) and to find those nodes which irritate you. It should be used sparingly, since you won't see evidence of the node in the TOC.
NOTE: "Hide Node" only covers the TOC method of display. Other types of display (e.g. in Node subwindows and Event Streams) shouldn't be affected.
