Wanted: Cookie categories in web browsers

Given that I delete my browser cookies fairly regularly, it would be useful to be able to divide them into categories.Then I could delete marketing and tracking cookies without affecting more important login cookies.

Some categories I would like:

1. Always delete at end of session (for security critical things)

2. Use standard rules

3. Delete at interval

4. Don’t delete unless I tell you

This is sort of confusing the idea of being able to delete cookies by category with overriding the default rules on expiry, but it mostly gives the idea.

I think what I really want is a function called Delete unwanted cookies which would magically determine which cookies I want to retain and which I want to delete.
