The advantage you have mentioned is the one I was pointing out… I totally agree. I have explained about the maximum, minimum and current values. While I don’t know much about the file category, the “Type” parameter refers to the type of value you want to have. If you want your new parameter just to take integer value, for example, you’d better choose “integer” so that if a user enters a floating number mistakenly, it would be saved as an integer. If you want a parameter with true or false values, you can choose “boolean” as the type. There are options allowing loading from a file, choosing from multiple choices or loading the parameter from a file.
