I'm not entirely sure myself, however there appear to be quite a few frequency based things around that are intrinsically event driven, and they aren't all 5 years old :). There isn't - sadly - a single bug / design aspect that I can point to and say 'if that were better, everyone would reach for this tool first'. If I were to make some guesses - the system (AIUI) requires a bunch of manual work to provide a robust debuggable 'do things later' mechanism, on a case by case basis. So adding a table is pretty high friction; writing new UI's for the same table is pretty high friction. -Rob _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
