Here is a simple plugin I'm making public because I'm sure it will make peoples lives easier. It allows players to easily change the precision, rotation, and length of pnb (and any object!) without having to repeatedly type in the console command each time.
The plugin listens for the user to press the U key and opens up a rudimentary (but functional) GUI at the bottom of the players screen. When a player clicks on a setting the GUI disappears and the settings have been changed. Please note, you can also toggle the GUI on and off by simply pressing the U key again.
It's an early prototype I knocked up for my server, but if you want to use it on your own - feel free to download!
Updated in version 0.0.2 - ability to set custom values and a slightly improved GUI.
