Wow, thanks for the high praise! 1) I think this is true of Poser in general; I'll add it to the list of things to investigate for v2 2) There's currently no way to query a lone checkbox without creating a callback function for it. I'll add this to the to-do list; in the mean time, just use a checkpane with one button. I'm not sure if this is something that could be added to PzrWidget, but I'll look into that. 3) I'm looking to flesh out the widget ranks (need to get multiple text entries in there as well) for the next version. Everything is still a bit cryptic at the moment. 4) Awesomeness. I had not considered looking at wxWindows (spent most of my time just picking through XML and PY files). Even if it's not fully exposed, that certainly opens up some documentation so there'll be less guessing what's going on under the hood. I wonder if we can rig up a hacked (but working) wxPython... Creating windows on the fly is fun and all, but changing their content interactively is king...
