Thanks for all your feedback!
Changed/Fixed:
1. Right mouse button over an existing operatorBox shows now an EditMenu, with following future functions: [Copy, Pate, Delete] (Paste will be moved later to the AddMenu). So its no longer possible to add a new operatorBox over an existing one.
2. Deleting any operatorBox.
3. operatorBoxes of each category (Generator, Filter, Distortion) has its own color.
4. Showing number of used operators in statusbar.
Next steps:
1. Try to add copy/paste of one and multi selected operatorBoxes will be added later.
2. Adding load/save functions to the control.
3. Adding keyboard support (Copy, Paste, Delete, Add operator/type)
4. Think about how to get all the nodes worked together and how to handle muliple input and output connections. (Seems its not like a tree of a TreeControl - i need some time to thnk about it)

@combakiing0:
Oh well... A possible and easy way how to use/handle the data structures making me a bit crazy atm! (as combatking0 said: it can be a bit frustrating ^^) I have really to think about it and wasting some papers here with possible drawings i tried ^^
@LittleWhite:
My first try/test of a standalone rendering engine with some very basic functions still exist and works in most case ^^ But is was just a proof concept and there are a lot things that will be changed / recoded or just say, coded again from scratch for the final

@Xetick:
I totally agree! Atm it really seems to be the hardest point to manage and understand how all the nodes worked togehter and how to handle multiple input and output connections. This really makes me a bit crazy
