I see, combinations. But also the ability to use different combinations of "basic" features in a sense are a specific feature too. Like you can mark text bold and you can mark text as representing a table. But can you mark text within tables bold? If you can that would to me be a "feature" too. If you can not, then that "feature" is missing.
