EVERYTHING in $UserBaseDirectory\Applications is an add-on, so it seems redundant to have one directory called AddOns, let alone two. "ExtraPackages" and "Enhancements" likewise appear unnecessary, uninformative, and redundant. Is there a user package that ISN'T an added-on, extra, enhancement? I don't think so.

Therefore, I suggest putting the package file directly in $UserBaseDirectory\Applications, edit it to remove mention of "Enhancements" from the BeginPackage statement, and load it with <<RootSearch` or Needs["RootSearch`"].

Otherwise, put it in $UserBaseDirectory\Applications\Enhancements (AS IS), and load it with <<Enhancements`RootSearch` or Needs["Enhancements`RootSearch`"].
