Nope. Thats the kplugins directory. That's why I made sure to mention that in my post. I'm lookin to specify a path for the plugins directory where java, realplayer, quicktime, acrobat etc.. plugins are installed.
To my knowledge the subdirectory plugins is always used and isn't configurable, that's been a Netscape/Mozilla standard since at least Netscape 4.x. The Gecko code will also look for the common Acrobat Reader and Quicktime plugins in their install directories and can also scan the Netscape 4.x plugins directory. There are prefs to disable these lookups, look in defaults\pref\all.js. Why would you want to use a different subdirectory anyway ?
I have MonkeeSage's builds as well as the SP1 build on my PC. They all have diff settings so I can't give them all one general settings directory which KM allows. But they all use the same plugins so there's no need to have four different plugins folders. Just wanted to save space instead of having to copy all the plugins each time. It's not something that is necessary. I just wondered if it was possible since sometimes there are other Mozilla prefs that I don't always know about.
I haven't tried this with K-M, but awhile ago when I found the page I tried it with Mozilla, and it seemed to work. Mabye it will work in K-M as well...
