Haven't found anything similar, but this is more about resizing components window in bpel. I know there is a way to resize font in ide.properties file, different windows sizes like
Ide.DefaultDialogWidth and height, file.chooser.width/height, Project.settings.width/height, new.gallery.
But I can't figure out on how to change a window size of Edit Assign component, it's really annoying to stretch it every time I open assign component especially when there is tons of variables/large tree of xml elements etc.
Has anyone an idea on how the edit assign property is called(if there is any).
