Some clients who are used to using things like Articulate have asked for the ability to add voice over some background music.
Maybe it's in the intro slide or whatever, but having a simple audio editor built-in could be a help in giving those creators who want more control the tools they need to move over to CREATE.
This could be for all ID's in any industry, and would not only add functionality but streamline the workflow.
As of now, if a client wants to have a voiceover with background music playing then they need to do it elsewhere and import the whole mixed file.
Doesn't need to be fancy, but have the option for 2 tracks could be helpful here.
