I was going to start a new thread requesting this when i saw yours. This would be an excellent addition to mIRC, even if available on the website seperately to normal binaries. Instead of COMPILING it or running it invisibly as a service, how about making it able to work openly like mIRC, but without all the irc server related options, including on*:scripts, etc. I've included an image on my idea of what it could look like.
