for the graphs, I guess I could do them for TE4, but once again, it'll be better to ask me on TE4 is done and I start to work on custom user requests...

For the code, it's TE2013 as it's C++. It'll be converted to C# (and partly rewrite) for TE4.
amg986,
you can beta test the demo of TEM2 hopefully coming soon, and if you like it, you can buy it... :p
