"user-friendly interface" → simple design (but "interface" is part of the phrase; perhaps "interface" stays. Wait, in the example, "audio editing" is split into "audio" and "editing", each getting their own synonyms. So "user-friendly interface" would be "user-friendly" as a modifier and "interface" as the noun. But maybe "interface" is a noun here. So synonyms for "interface" could be GUI. "User-friendly" could be simple. So the phrase becomes "intuitive GUI". Wait, the user's example used "user-friendly interface" as a single term replaced with "intuitive|simple|intuitive design|layout|interface" but in the example provided, they split "audio editing" into two parts. Therefore, for consistency, I should split the phrases into individual words and replace each.
