again digging thorw the documentions can't find example on how to detect in code that my plugin is loaded for the first tme .
i need to reset the 'LrPrefs'.prefsForPlugin() parametrs .
You can reset prefs-for-plugin by iterating with 'pairs' method and setting each to nil.
So, to tell if it's first-run, just set a pref every run (e.g. in LrInitPlugin module).
If that pref is not set, then it's first run.
