This is just a heads-up that I am developing a Default in-game (HUD) interface for the plyGame RPG module. It will be included free.
I am creating this with Unity's new GUI system and it will be source scripts directly in your project folder, not in a DLL, so that you may easily modify it to your needs. I hope that this will serve as a better example of how to do custom GUIs than doing guides on this kind of system. It is all done a scripts and not Blocks since events (Blocks) for user interfaces can get quite complicated.
There will be Blocks related to this interface and of course Blocks for the Unity GUI system.
