Mod name: Tip the Scales
Link to mod download page (must be CurseForge): https://www.curseforge.com/minecraft/mc-mods/tipthescales
Reason it should be whitelisted: Provides a 1 through 10 UI size scale instead of "small" "medium" "large" and "auto". This is useful for people with abnormal screen resolution (ie surface pros, macs, etc) to customize the ui size to their fitting. With vanilla screen sizes, large is way too small, and the auto option is way too big.
Mod name: SAO UI
Link to mod download page (must be CurseForge): https://www.curseforge.com/minecraft/mc-mods/sao-ui
Reason it should be whitelisted: provides an alternative UI that can be useful for a few reason. A numerical health counter instead of the standard vanilla hearts which is useful for people who have more health then the heart counter can handle. A vertical option for your hot bar and other ease of life upgrades
