If you did a search, you would've found that there have been a lot of posts regarding similies, emoticons, graphics, etc. and posts both for and against these items.
mIRC is an IRC (Internet Relay Chat) client. Chat clients, which are text based, have been around long before Windows was even introduced. Possibly even before MS-DOS (Microsoft Disk Operating System) was out.
There are other clients and add-ins for mIRC that already incorporate/allow most, if not all of the things you have mentioned, but it appears that Khaled does not want to incorporate them into the main program, based on the amount of time that has passed since these were originally suggested, and the number of releases since then.
