So if you have a boolean, the default should be "true" or "false", not "Enabled" or "Disabled" (your possible text displays) nor 0 or 1 (index values). Similarly for int value, it's 0, 1, or 3453463, or whatever.

I find this more cumbersome than it's worth so I don't bother, though it may be a good idea if your project is large and / or the preferences change a lot. Mine don't. Suppose I want the default choice to be Fahrenheit.
