as a delphi developer I was used to those node network between tables object in each database some of the object are visible and the others no .. but there always a text object (or a comment) that we can link to each group to comment this...
what I suggest to the developer staff of TG2 is to Add a text object or something that we can put into or link to each group or way not to each node to leave some comments links those in any development language ... if we leave a project for a period and come back to it we can read the comments in each group ...
I think that is something not hard to add i the previous release ...
