SerializedUdonPrograms end up being thown into a "SerializedUdonPrograms" folder and given a randomized string for a name. This is really annoying when creating prefabs as it's very unclear what assets should be shared.
These files don't clutter things too badly. It would make more sense for these serialized programs to be saved next to the asset that generated them.
In addition, it should be made easier to see what a serialized udon program was serialized from via a human-readable name, rather than the randomized string they currently use.
