I think it would be a good idea to have the following as optional:
– Options.txt to not be overwrote on every update (only updates that directly affect it)
– HWYLA (https://www.curseforge.com/minecraft/mc-mods/hwyla) – Shows you what block you are looking at and what mod it is from. (https://www.curseforge.com/minecraft/mc-mods/hwyla/files/all?filter-game-version=2020709689%3A6756)
– Inventory Tweaks for quality of life improvements to the UI handling. (https://www.curseforge.com/minecraft/mc-mods/inventory-tweaks/files/all?filter-game-version=2020709689%3A6756)
– Optifine (http://adfoc.us/serve/sitelinks/?id=475250&url=http://optifine.net/adloadx?f=OptiFine_1.12_HD_U_F5.jar&x=14b9) because Optifine is great at reducing lag in computers.
