[Geek Alert!] Allow me to rant about Autodesk® Maya a bit. I don't think I'm the only one doing some UV editing after rigging and it would be nice if that history could just be deleted, just like normal modeling history. But that would be too easy. Finally found a workaround with a MEL command (polyTransfer) which is of course quite different from the very similar menu reachable "Transfer Attributes" I got the result I wanted in the end luckily.
