Note from pai: i² is a 'full' script written for mirc 6.01. (a script designed to do a lot of general tasks, as opposed to an 'addon' script with one specific purpose)
Note from acvxqs: I had to make a slight change to the alias cfg and update the flags given to the window command. I am unsure in which mIRC version /window -h changed to window -w0, , but I estimated that this happened around mIRC 7.18, hence the script version bump from mIRC 6.01 to mIRC 7.18. Also I bumped i2 from 1.07 to 1.08 to denote the change.
The script is notoriously difficult to read and hence fix, should there be any bugs. But feel free to talk to us on EFNet in #peace&protection, or log an issue over at GitHub: https://github.com/peace-and-protection/i2
