actually i agree with demon on this. "theres only so much a window can do" actually mirc has barely touched what a window can do. even picwins are very limited in alot of aspects. if someone were to make a list of all the things that arent a MUST in mIRC that list would grow in heaps and bounds by every version. in fact what do you really need? a way to connect to a network a window to display text in and an edit box to send it. it works but what kind of experience would the user get from it? as for the nicklist it wouldnt take alot of processor power to do. i have a dll that does it quite nicely. having more control over the nicklist built in would be a great improvement. as for emoticons i can take it or leave it. the point here is none of it would be sent to the server. all the server gets is the plain text form mirc translates it (if the option is enabled). this will indeed take more process power to do but not ridiculously so. for those of you who join mp3 channels and others where text is flying by at 1000 lines per second well you may wish to disable this option.
point is new features is the idea of progress. we could all be using windows 1.0 still as well but we dont.
