Would be nice to see some way to block some updates. AuctionMaster is not hosted on WoWI but Minion finds
http://www.wowinterface.com/download...ionMaster.html and offers this update.
Some others are not up-to-date like Postal so an update might be a downgrade.
For AddOns like Postal I'd like a feature to lets say use svn as update mechanism. When marked as svn-repo and a tool like Tortoise is installed perhaps there could be a button to update from repo
Edit: To identlfy false positives it would be nice to see the AddOn-Path for the offered updates.
