One of the most powerful feature in my opinion is to create and use custom fields. However I'm not sure whether this is possible at the project level...
I'm asking because I want to add some details at the project level (not issues level), details like: Contract link. Expected Start date, Expected Complete date, number of allocated development hours etc....
All of those data would valuable at project level so that we can monitor projects at a higher level.
Here is where I would love to see the fields appearing:
Projects/TopSecretProject/Project settings
