Hello, the most important thing that has to be fixed for me actually in pd-extended is the ix extension, so let me try to add a doc file that might help for using those widgets, it's attached. I've copied and pasted the text from the psp file we can find into CVS extension/gui/ix I've forgot to tell one thing, ix extension needs tcl-tk 8.5, so it can't be into pd-extended because it uses tcl-tk 8.4, weird isn't it? Also I suggest to put the dll's of the required tk libs for the windows installation of pd-extended. any comment is appreciated.
