Currently you only allow the Below settings to request the list data for scripts, what would be a good idea would be to have another option for tempban expiry time, example:

$ibl(#mirc,1).secs - returns seconds till ban expires (returns 0 if no tempban expiry is set)

eg. $ibl(#mirc,1).secs = 478

---
from mirc help file:

$ibl(#channel,N)
$iel(#channel,N)
$iil(#channel,N)

$ibl(#mirc,1).by returns the address of the user who set the ban
$ibl(#mirc,1).date returns the date when the user set the ban
$ibl(#mirc,1).ctime returns $ctime format for ban date

Yes, that is very good idea! also make it working with the $iel #iil identifiers too.
