When entering the support details for a contract it lets you enter more text than is saved. If there is a limit on what can be entered here it should really be enforced in the user interface instead of truncated upon submission.
Also once a contract has been created and saved you cannot then go back into it and then attach a document which can also be a bit annoying.
