Are the tools any better for experts? An expert developer
might be able to navigate or at least understand the sequence of
error messages created in these use cases. Accessing the tools,
however, would require repeated alternate use of the mouse
and keyboard. One might even expect an expert developer to
intentionally avoid all such errors by executing the cases in a
specific sequence (i.e., case 3, 1, and 2), but doing so would be
no faster than manual development. On average, expert users
may not even make use of available tools because they offer no
advantage.
