Currently, it seems the intended way to learn Persistence outside of the documentation is through the examples provided in the Example Central. However, all of these examples only use U# and no Udon Graph. In fact the ONLY Udon Graph example for persistence is practically hidden all the way at the bottom of the PlayerData page, under a massive table. How are graph users ever suppose to learn this?
I request that the Persistence examples in Example Central (Position Sync, Persistent Pen, Persistent Idle Game, Leaderboard, Persistent Post-Processing Settings, Player Data Types, HealthBar, RPG, and Unlock Items) include Udon Graph examples as well.
(Also while you're at it, Mute Others and Player Join Zones could use some Graphs as well)
