At present, when you've added a property to an item at a basin, the only option is 'Done.' which kicks you out of the dialog box and necessities clicking on the basin and starting the conversation again. Which is more often than not, when you're trying to put six or so properties on an item before it's finished.
It really knocks a person out of the clicky-clacketey dweomercrafting fugue state.
It'd be a nice QoL change if there was an 'Add Another Property' option added which takes a character back to the property selection window.
