Hello everyone! I present a simple and a very lightweight solution that will suit most your scoreboard needs!
Note: this plugin is for a server i am developing so i wont really be updating or fixing bugs unless they occur on the server i develop in. If the plugin gets more popular i might decide to regularly update and add features for it, for now its just a simple project that im sharing here 
COMMANDS:
/reloadscoreboard ( realoads config file of scoreboard, permission : "scoreboard.admin" )
Author note:
- Distributing this and claiming as your own is scummy, lets avoid that
- Although legacy can work its really not suggested to use on servers with version 1.13 and below
