I used ptree for saving configuration numerous times. I don't quite understand what you mean by "smooth", but for me it was adequate without notifications. In my case, saving was usually done in a destructor of some high-level class, something along these lines:
~Application() { write_xml(m_filename, m_settings); }
This is not acceptable for me. Setting should be stored as soon as they are changed, just in case your application crashes or is killed.
If you need notifications - and I'm sure there are cases where you must have them - this is the wrong library.
I don't think this is the wrong library, I would argue this is the problem with property_tree library. Wanting to be notified when a tree changes is quite reasonable thing. - Volodya
