Currently when a filter or processing rule is changed one needs to click the "Replace" button to save the change. However it is possible that one has edited the rule and forgot to click "Replace" in which case the changes are simply lost without undo (which can be annoying). So nothing provides a way to: - remind the user of unsaved changes - see that the rule has been changed It would be good to have: - a reminder which shows up if a rule is not saved - a visual cue indicating that the rule has been changed but not saved (e.g. make the line bold) This suggestion is also for the sub-dialogs for condition and action editing where the situation is the same.
To clarify: this is a suggestion about individual rules when one switches from one (edited) rule to another (I know there is a global reminder if one tries to exit the rule editing interface if the currently selected rule has been edited but that's different)
