Holdlook Minecraft Mod
This mod adds a simple one button to go from first to third person. There's currently no toggle feature, only hold, but I plan to add a toggle if people request it / people use this mod.
I made this mod because Hypixel blacklisted the perspective mod, and Lunar Client and BadLion didn't have their 'Snaplook' type mod public so I just made it myself...
