==== Background
The IP auto-reveal feature lets certain trusted users enable a mode where temporary account IP addresses are displayed by default next to their name (in most places where the user name is displayed). This is to aid patrolling work once temporary accounts are rolled out.
Currently to enable the mode, the user clicks a tool link, then is asked to choose an expiry time (1 hour or 30 minutes), but we have heard feedback that this adds too much extra work for patrollers on wikis with a high volume of edits.
This task is for making a seamless version, where the tool link toggles the feature on and off, and there is no expiry. This should be configurable to avoid disruption on wikis that currently have the feature.
==== Specification
When a wiki is configured to use this mode:
* Clicking on the tool just toggles the mode, with no dialogs shown
* There is no expiry time when the mode is on
* The log should not include an expiry time
