and is posible to every nick have diferent color like ( http://addony.parba.cz/mirc.png ) - xchat has only colored nick function, but it is not good ): ?
nick alignment can be done with mIRC theme (haltdef) scripts... and a little creative thinking :-]
nick coloring can be done already, check the address book (the thing between remotes and online timer) and add masks at the last tab... there you can color nicks
