Auria, I'm hereby passing the development of the property browser back to you.
I just can not get used to the new Blender API. It's really driving me around the bend (you must have read my posts at blenderartists.org) and I feel this frustration is preventing me from continuing. I hope my decision to back out is not too much of an inconvenience for you.
Thank you for letting me work on the property browser all this time any hopefully I can be useful in other area's of this project.
