I recently found myself wanting my own offline list similar to the one from
http://petsear.ch/Pets. It would be so much easier since battle.net is slow to gather info about your newly obtained/newly leveled pets.
I would love to have the same info as petsear.ch in a spreadsheet that you can snag from in game. There used to be another addon for gathering guild information in the same way (from in game, copied so you can paste to a spreadsheet) but I cannot recall the name of the addon.
