I had been putting this off for too long, and I suppose the demand and utility is now too great to ignore.  So I am including this addon in XBar.  I named it XPortalsBar, so that users who prefer the fan-created XPortalBar may enjoy it in peace.

I would really like to thank dtylerb and Ravenswing for doing an awesome job in the absence I was forced to take.  This mod would not be here without their support, and the support of all who use XBar.  It is not my intention to step on the toes of aspiring authors, and I am both humbled and grateful that they enjoyed my creation enough to undertake this project.

XPortalsBar includes all the fancy goodies of the other bars, including bar wrapping (so you can have them all on 2 rows, teleports on top, and portals on the bottom), button hiding, and reagent counting.  Now also supporting Horde factions, and outland cities.
