I think we should change the default PotFog tool within FB ("PoT Fogger") to "PotFog from Visibility," since most offices are using DAS anyway and should have good quality Visibility grids already created. I guess this could be configurable as an option, too, but I just feel like the default tool is so basic compared to creating the fog from visibility grids, and this would ensure better consistency between our aviation and gridded forecasts. I know this isn't perfect since there are multiple possible reasons for lower visibility, but fog is definitely the most common cause of visibility reduction.
Alternatively, there could be a GUI to allow the user the ability to select the best tool for the job instead of defaulting to the Fogger tool, kinda like how the PotThunder tool used to work (and will work again in a future update).
