I'd request the ability to set a default action duration (2, 8, 24) for all unknown or new auctions. It's a lot of extra clicks to just set everything new to 24 if you like to do that.

Most of the players set their auctions to 24 hours so yes, please implement this feature.

You can now change the default with /aux post duration 24 (warning: when upgrading to the newest version you lose your history)
