If you had never explicitly set anything up then you would have the default settings. Once you set up any setting then the ones displayed get saved and used going forward. I pushed out an update earlier today to give better defaults for those who never change any of the plugins settings.
Did you read the built in help regarding how the heat pausing values work? If so and it was not clear maybe you can mention what you found confusing to it can be improved.
It is possible to revert to default values by either deleting the .cfg file in the plugins folder on the flash drive, or by removing and reinstalling the plugin. I will think about whether adding a Defaults button adds value - it would be trivial to implement but may be unnecessary now I have mad the initial defaults more like what a typical user would want.
