In addition to clickable documentation links, the FBDK now generates hoverable pop-up documentation (derived from comments in the XML document) for graphical elements in the PNG diagrams produced using the "Save as HTML" function. For a user-oriented overview, see the FBNavigator home page, and for instructions on producing the HTML documentation, see https://www.holobloc.com/doc/fbdk3/howtodoc.htm.
If you are already using FBDK 3.2, this update will auto-load at startup; otherwise, you can follow the instructions at https://www.holobloc.com/fbdk3/index.htm.
