Have just had a quick play with the latest version of EA and discovered one feature that I've been yearning for since I first started playing with it. In fact, it's one of the main things that put the BA's off using it for Use Case analysis.
You now get to add Rich Text Notes to elements! This is especially useful for documenting the steps in a Use Case scenario. Previously you had to manually number the steps in a plain text area.
Now you get to be able to do this.
Now that's better.
Looks like there are more new features in 7.1 than were introduced in 7.0.
