Thanks so much to all of you I can promise it's just the beginning of P3dO. I'm currently working on a much better tree view and severall improvements in navigation and thumbs loading. This version's nearly finished and will be available on my site late may for trials and here when it'll be free of bug. BTW: P3dO means "Poser 3D Objects", that is to say 3D will come in its time ;) All this for free: P3dO is a Freeware and will stay free Yarp
