i guess someone post about it before just did not see but in case.
Pluging code editor has this funny bug that start jumping the screen from bottom top like animated . it happens to me about 10 times a day when using editor.
Yes, was one thing I discussed (briefly) on IRC, when you right click on the same shader (or plugin) from 2 different node instances, it opens two code editor windows, when you save it then thinks it’s always in a changed state.
Hope that helps a bit, this part is super simple to reproduce.
Best (correct) way, have one code editor window per physical file, several just doesn’t make sense.
PS : I love how vvvv can manage to confuse itself ;)
