Hi Steve,
In the FEA Editor, the coordinate systems are used for loads and constraints. As Andrew indicated, you need to assign the nodes to the coordinate system (by selecting vertices, surfaces, etc > right-click > and whatever the command is to assign the selection to a coordinate system) before you can see the coordinate system axis appearing on each node.
In the Results environment, the coordinate systems are used to transform the results. However, there is no visual indication of the coordinate system. The software could replace the cartesian mini-axis with the user-defined coordinate axis. (You could make the same argument for the FEA Editor so that you can "see" where the new origin is, but it is a little misleading since the local coordinate system only applies to selected regions of the model.)
You may want to check the Idea Station to see if this suggestion has been made and either add your vote to it or create the suggestion. I took a quick look but didn't see the suggestion. [Edit] I think that this suggestion covers your idea although you may want to elaborate (add some comments and/or images to the Idea) on how you would like it to work. symbols for loab/bc when local coord syst defined
