I'm talking about what is convenient for the users, not for network owners.

So am I - And indeed I am not only speaking about procedural fairness, I am speaking about the patent stupidity of putting a feature in a programme that is suitable only for users who use four out of hundreds of networks.

As I speak there are 1,307,008 users on IRC (quoted from irc.netsplit.de) and 519,626 on the Big 4. So you arn't even representing 50% of users with your second suggestion. Infact you have a shortfall of around 300,000 who probably don't know or care about the Big 4.

I reiterate that any feature in mIRC should be suitable for all users.
