Here is an other idea for helping with code quality.
What if IDEA checked certain set rules(like always these would be configurable) ad alerted you as soon as you broke them. I see this as a hybrid of Intentions and Inspections.
For Example: you have a project which contains some api/framework packages and implementation packages, or it is made up of separate blackbox components and you want to make sure no action, refactoring creates an unwanted dependency. I would really like it if somehow this was checked I was alerted as soon as I did something that broke this rule.
These would be specially useful when doing some refactoring and your going to touch a lot of classes and would like to make sure you don't break this rule.
The key idea here is that you are alerted to a problem right away while you are within the scope of the problem. I often find that with code inspections I am afraid to apply the inspection suggestions because I often don't have time to assess all the suggestions being made.
ps: hope no one is minding all my posts this evening... I am feeling specially inspired!
