Alright, I have added a new page in the webui called “player interactions.” This page will list all online players as well as list a few options available to dealing with that player specifically.
One thing to note: there are not that many clean ways to get a list of players available on the server except through Minecraft Query. Most servers have this off (it’s the default), but this functionality is required for this page to appear–when the server is started (or restarted) with this property on, this page will show up for you.
server.properties -> query-enable -> true.
