I am currently working on a searchable potion list to help admins get the ID and Data Values for each potion and to replace my old one. It can be found here. To create it I am using Github Pages with HTML, CSS and JavaScript and the following librarys: Bootstrap jQuery (My first time) If anyone would like to help, please make a pull request.
Which is awesome (yay ), but bad for vanilla creative servers (people griefing whilst invisible), It would be awesome if there was a bukkit.yml option to override OP's being able to see invisible players... EvilSeph ?
Bukkit will not add features that normal minecraft does not have... I would try posting in the Plugin Requests forum. But back on topic, this will be a very nice tool for server owners!
