CMX_CMGSCCC,
I have another question for you. I haven't tried creating any hacks using the plugin system yet so I don't know if this is possible, but it might be something to look into, if you're also thinking about optimization.
I've read that the plugin system stores all the code into memory, which means that the more plugins you have, the more memory is taken up to store the plugins.
My question to you: would it theoretically be possible for you to dump all the plugins into individual php files that would be contained in a plugins folder, and then referenced? So instead of having the actual code in the plugin system,
have them in files.
Just something else to consider...
BTW: This is really a great product.
I know I could probably do this myself, but with the amount of updates you release, it would be a major problem have to do this over and over again.
