Well in this particular case every layer has a name. The ideal is having the
name next to the en/disable property. Save a document with the layer manager on
it. When you open it all the layers names went down.
I believe respecting the order is very important for the coherence of GUI in
general.

opening a file with already created properties from a script on the script node.
Like now (when opening):
1- Creates the script.
2- Evaluates the script.
3- Add the user properties. (without checking that they already are if the
script created them)
You may test this also loading a file with a layer manager. This only happens
with NullOutputScript.
I guess it should evaluate the script after adding the properties.
Cheers!
