Everything aside from the sorting and checkbox idea is okay and will definitely be added.
Sorting is an issue because Torque doesn't like it, but ill see what I can do
check boxes are virually impossible because of the way list object work
I can understand the check box being difficult, but the sorting by columns should definitely be added. It's used in the player list to sort by admin, name, ID, and trust, so I would really like to see it in this add-on. It would be really helpful when searching for bans, especially if you need to sort them by when the ban happened (which bans are the most recent).
But yeah, you don't need to add the check-box option if you find it too difficult. That can be optional.
