You have a point there. The Preferences panes often don't work at all correctly, I'm not really sure why. For example, I added a flag in startups, but then the flag stayed on afterwards, until I edited the registry.

On Windows I found you have to Apply the settings and Save them (a couple of times for good measure) before they stick.

There's also a limit in the amount of libraries and directories you can add, which is a SERIOUS shortcoming.

The available edit windows in tcl/tk are a bit limited. It seems like you can either have a one-line editable field or a whole rectangle that you can enter any text into. With the one-line fields currently used there isn't enough room for more than 10 unless someone adds scrollbars to the window. Just entering a list of libs in a text field is not so far different from editing a text file. Maybe a button "Add Lib" which pops up an line edit box. An uneditable list of existing libraries with "Edit" buttons next to them? Same thing for paths.

However, this still leaves the problem of having two PD's installed at once. Any suggestions on how that should be done?

If each Pd had its own prefs file... http://wiki.tcl.tk/3919 has a code example in tcl that could be modified and put in pd.tk as an interface to an xml file.

The reason I had to install two PD's, is I'm using a brand new experimental version of Gem, that crashes PD-extended. But help fiiles don't work for me in Miller's PD, so every time I want to check a help file, I open PD-extended and use that browser. I am essentially using Miller's PD, with all the extended stuff dumped into the extra section of it, as Patco suggested.

Anyway, finally, even though I edited the registry by guessing, I'm still mostly clueless what the entries do. Any chance of getting it documented? Is it documented in some other form I just don't realize?

You can look at the source in s_main.c, the function sys_argparse has all the possible entries in quotes, but they are not explained and also don't seem to correspond exactly with their names in the registry.
