Hey Grady - thanks for "filling in the blanks".
Allow me to clarify two items:
Your example states to add "dir1/page.php" - and I notice that you omitted the leading slash. Is that intentional/required? In other words, it wouldn't match a "starting with" or "exact" of "/dir1/page.php"?
Secondly, if I understand you correctly, the "Dynamic Pages" you configure in "General Settings" are in no way related to the "Dynamic Pages" in the regular reports? Also, they are in no way related to list of File Types that you can configure system wide?
Assuming that being so, then I believe it's non-intuitive to use the same terminology to refer to two completely different sets of features. If the General Settings are really about "Query Variable" harvesting and don't even require the list of filetypes to match the "Dynamic Pages" file types configured elsewhere in the system, then I suggest calling it something different (e.g. General Settings -> "Query Variables")
Best Regards,
Andy
