We hope this will make Skyline more fun to develop mechanics in, rather than the worry of cross language/format syntax errors and as you say, tons of code to do something that should be simple.
Thanks for the respect
Update
: I have managed to get a file to load back without the presence of the graph editor. Although this still requires QT to still reside in the engine which will be a problem when we go mobile. But doing it this way will let us to be able to release the graph system for PC production and overcome the removal of QT when the time comes. There is still months of work to get the graph system polished but it is becoming usable if you don't mind the odd wort and organisational gremlin, but isn't this the case with a lot of Skyline!
We are looking at a release asap with the new Nav update and many other fixes and we will try to get a functional graph version ready for the following update, so fingers crossed
