If I want to disable such properties for some devices I can change it to read only or have to modify list and put settings in device's resource directory.
But position is the same like in default settings.xml.
It'd useful to:
- add flag hide for all types of properties (I don't know what is a problem to add read only to lists) or
- add functionality to define order of settings - the simplest order should be defined by properties.xml not settings.xml so I can add files to device's resource directory and in
-- properties.xml is order and vdef values
-- settings.xml only change view
Now, user have to see and scroll for settings that are not for him (if there will be no hiding I want to move properties to the end pf settings).
