for some reason the code that i edited in a NavLeftItem always return to the old value. I edit, change the window and when i open again after i run the project, its with the old value.
You can see a movie that i did.
Thanks @Luiz D'Aniello (I receive your project by email).
We identified (and fixed) a bug that affects separated code editors only, as a temporary workaround you should use the inline editor.
A new version with this bug fixed should be released within a couple of weeks.
