As suggested in a different post, following up here with the suggestion.
Suggestion
Rules should have a title and description field.
A user may wish to set a generic title such as ‘Rules governing task completion’ but also have a description where they define the logic of the ‘if-this-then-that’ behind the rule, without needing the user to be well versed in the structure of the rule building tool itself. This could be useful for providing much more information to end users about the operation of the project and why certain things happen based on rule triggers.
Granted you can add a large title which does display on hover in the customise menu and this would likely only be applicable to those that really want that finer understanding of the system thats been built, but it could prove useful.
It is somewhat in keeping with various other aspects of other Asana features (like custom fields for example) where they have a title and description field- admittedly this is obvious as to why specifically custom fields are set this way.
