But propagating a plethora of preferences in perpetuity is poison to reproducibility. So it should be a setting of the context, which is initially disabled.\n\nSpecifically, by default, when you spin up a new context, the `PrefService` should _not_ load values from persistent storage, and should _not_ save them there either. It should keep the settings _only_ for the lifetime of the JVM. But, if you call something like `prefService.loadSettings()` then it should load the settings from persistent storage, and save them there each time as well for the lifetime of the context.\n\nThen, we can add an `ij.prefs().loadSettings()` call as one of the steps in `net.imagej.Main`, so that the default application behaves that way. But people doing low-level things, unit tests, etc., will not be bitten by that inconsistency.\n","author":{"url":"https://github.com/ctrueden","@type":"Person","name":"ctrueden"},"datePublished":"2015-03-03T20:06:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/150/scijava-common/issues/150"}
