yes , i want a ferrari with a fiat engine , i just want skin support for mirc then you can stay happy with classic interface and i can be happy with new skin, and i don't care that skin will reduce stability...

The priorities are in the wrong order. Personally I would prefer stability to be priority number one and I am glad that the effort in the last unpgrade has focused on this.

Make sure stability is good, then worry about what the programme looks like. Having said that I like mIRC the way it is. That said, 'looks' is a matter of people's individual opinions. mIRC is neither good or bad simply because of what it looks like.
