Hi Jules53757,
Thanks, your support to P3dO is really appreciated.

I've been thinking for long in adding the ability to add Runtimes directly from P3dO but it is not a priority - I don't know if Poser will take it into account on the fly.

On the contrary you may already save items from P3dO. There is a Save command in File menu. The new version of PoserPython (2.3) renamed that command to "Add to Poser Library" and also added that button as a command on the InDepth panel toolbar for easier access.
On PoserPython 2.2.8 and 2.2.9 that command is unfortunately bugged (PoserPython 2.3 is available on my website with the Poser plugins pack for P3dO pro - I don't recall if P3dO 2.2.5 will show the new button on the InDepth panel but I think it will). Anyway P3dO 2.3 will be available soon.

Compared to Poser the great advantage of using P3dO to save items is that you may quickly save to another directory. The feature is yet to be improved for even greater flexibility in selecting the directory.
