(Yes, I'm stealing everyone's words.) ;-) Must have's: Reliability. Stability. Backwards compatibility. (You know what I mean.) Undo feature. (At least one step regardless of the last action performed; several levels would be nice.) Strongly desire: Library hierarchies. (I can't go back to P4 now that I have nested folders, something that P4 should have supported.) Ability to create library folders and move files from within the program. (I have to shut down Poser and do this in Windows Explorer. Sigh) Would appreciate's: Compatability with other programs like Vue and Bryce. Ability to display transparencies in the work mode, not just render mode. Manipulate multiple objects at one time. A way to save MAT and MOR (or thier DAZ equivilent) files directly.
