It will be cool if Khaled releases a "Lite" verision of mIRC, without some of the integrated things (Options Dialog, Links, Notify, etc) and some extended features (like changing the options from /commands, a console with all the raw irc data (instead of channels, status, etc windows)), that allow us (the scripters) to customize the functionality of mIRC. It will be great, per example, if we can script our own "client". mIRC Scripting Engine it's great... and will be cool if we can use (and abuse) of it, to make a "client" using mIRC.
So... the only thing needed is commands for "everything" and less "dialogs" and "integrated stuff"... I think that mIRC executable will be a lot smaller and sexier to us...

In resume, mIRC Lite will be the main window, a console window (for debugging, etc), and the mIRC Scripts Engine...

mIRC is cool, has a very nice friendly interface, but... mIRC Scripting Engine is cool!
