Hi Nicholas,
Am I correct in noticing that the docs on the WP Admin Tools are a tad out of date?
There is, for instance, talk of a geolocation feature which is no longer provided (a shame, but I noticed geo location has become a bit messy so not that surprising).
I'm basically going through the whole document right now setting it up so it's quite noticeable :).
While I am on this topic, could I suggest that purely to prevent too much support enquiries you make the resulting full URL visible below the "Change admin URL" feature so that someone at mysite.tragic.com setting "banana" as their admin URL will immediately get a heads up that their login URL will become mysite.tragic.com/banana the moment they save this (or show the site URL before the magic word so what they fill in shows the full URL).
I too have had moments when there was too much blood in my caffeine, so a small hint is always welcome 😋
Cheers, P
