Make Shader Forge work from Left to Right

I always wondered why they (Epic) were doing it the way they did in UE3. Asian customers?
There are quite a few applications out there that have node editors that go right to left as UDK does.
But there are a few things to consider when switching the flow direction as stated by Joachim in this post:

Yup, at least he says it's trivial to implement - a toggle in the UI would be great :)

The primary reason I kept it right to left was to make it immediately recognizable for Unreal 3 users. Ironically, Epic themselves reversed it only in the last month or so.

But yeah, as I outlined in the post - another advantage is that the preview is on the left side, which makes sense hierarchally.

Shader preview <- Main node <- Your node tree <- Node browser

Reversing it would make it look like this:

Node browser -> Your node tree -> Main node -> Shader preview

I would be uncomfortable with the 3D preview on the right, and if only the nodes themselves are reversed, it's no longer in a neat order. What do you think?

A toggle in the UI is a tricky thing, because it will fragment the userbase when people take screenshots of trees in the wrong order

Um I don't mind the preview on the right either, its how I use Unity, the default layouts tend to have the preview bottom right and I am used to that. I am actually happy to keep that either way that suits you. My main desire is the nodes themselves.

I assume you meant

Node Browser -> Your Node Tree -> Main Node -> Shader Preview?

I did, sorry, fixed now :)

Ah yeah thats true about screenshots.. I suppose Unreal users are going through that now with so many v3 screenshots right to left and now having a left to right editor - I am MUCH preferring Unreal4's editor :) - not over Shader Forge of course - over Unreal3's one ;)

Just being a pain here but as of now..

Maya ShaderFX = Left to Right
Cinema4D CmNodes = Left to Right
3DSMax Slate material editor = Left to Right

Source Engine shader editor = Left to Right
Unreal4 shader editor = Left to Right

;)

Houdini, Left to Right

Softimage (XSI), Left to Right, Worldmachine aswell... but to be honest i dont mind the direction. 
I think the preview and node browser should stay where they are, node tree itself could be flipped. For me its a minimum priority thing though

Whoo great news!

Would be possible to keep both options? I have worked years and years with the old UDK, so... :) I feel more comfortable with the right 2 left style

As do I, but I got comfortable with it after about 5 minutes; I think you will as well :)
I'll probably force it to only be in one direction for consistency among users, especially those making tutorials/screenshots.
