1. Start using UTF-8. The entire world has already adopted Unicode, there is no reason for mIRC to regress to obsolete encodings. Unicode supports just about every single language, including Cyrillic, so it should work perfectly for you already.
2. You can already use images as backgrounds in windows, see /help /background
3. lol @ gif animations. This has been requested many times. FWIW, Unicode also solves this problem with things like
Emoji, so yet another reason to ditch your old ANSI encoding.
4. This probably won't happen in your lifetime. If you want this, I hear there's a chat client called Windows Live Messenger that might do what you want.
