So I downloaded this plugin for my Survival Server. My scoreboard is basically just showing players Health, Name, and Stats. This plugin has done everything I need it to do!
First, very good plugin, just that you have one or another error, let's start with the support of PlaceHolderAPI, (because in your only class you have not registering the plugin), when you use / sb an error appears in the console, since the dependencies do not work I have no idea if it is FLICKER or not, but, due to BukkitRunnable, most likely yes.
Now, let's talk a bit more about the code, so I see these abusing "finals" in the Lol strings, another bad thing is that everything is in a class, I recommend making other packages or just other classes, both in the config .yml you should put an "enable" in each line, because if you do not want to use the 15 lines they will be empty, and that bothers you.
