This is a feature request as stated by the forum topic.
You could script colors for nicknames yet Khaled saw
fit to add userlevel support to Nick Colors. And in case
you didn't know he added userlevel support to DCC send
under Trusted Users.
I can script about anything I can imagine in msl.
I'm sure I could script an ignore and exclude for every
event for every userlevel but I am suggesting/requesting
userlevel support within the ignore/op/voice/protect of
the address book to aid in further developement and
improvement of the client.
Imagine if you could simply add nicks/mask to user levels
with a scripted popup and then with another set of scripted
popups manage how you wanted to allow or block or op or
voice etc those users by the level you assigned them. The
addition of user level support within the address book would
not replace scripting, it would just simplify and improve
how user levels functioned.
Also, while I am on the subject of the address book, it
would be nice if it had an auto-help-op tab under control
to go along with the user level support. Also maybe better
support for help-op all arround as in events like: on @*:Text
why not a on %*:TEXT etc etc
