I'm working on the feature request [0] and having some troubles with adding table comments as tool tip in the navigation tree. Tool tip can be display by adding title attribute to line [1] in NavigationTree class. But I'm not sure how to access table meta data (table comment) at that point with $node object. Is it possible to do that ?

Or can we set table comment in the constructor of Node_Table class by setting another array element to $links associative array [2] ?

Is there any other approaches. Appreciate any help.
