Going to do some more updating
I plan to make some more changes to your basic plugins wiki page. This is an outstanding start which I wanted to do for a while. You have encouraged me to actually do some of this. There is some interesting things about parts of the code that you have that I'd like to explain.
I'd like to turn these pages into a series of tutorials on plugins. The trick is that the gen_ plugins and ml_plugins are probably the most commonly used. We can go back and do some of the other types at some point but they tend to be more specialized.
I think the next step will be to expand your basic plugin to retrieve information from the Winamp core. I'll let you know and you can look at it. After that we'll talk about creating a dialog that can invoke methods in the plugin.
Thanks for starting the page.
