Thanks for naming it. The concept is good. Whether it can work depends on whether the db layer we rely on has a notification mechanism for db changes we can hook into. The current db layer is provided by libdbi, which is not managed by the gnucash team and I haven't looked into this yet. That's where my "I have no idea" came from :) Geert _______________________________________________ gnucash-user mailing list gnucash-user@gnucash.org To update your subscription preferences or to unsubscribe: https://lists.gnucash.org/mailman/listinfo/gnucash-user If you are using Nabble or Gmane, please see https://wiki.gnucash.org/wiki/Mailing_Lists for more information. ----- Please remember to CC this list on all your replies.
