I'd love a feature where I could change the default blue colour to red or green or whatever, depending on my editing process.
When editing, I have to use a separate notepad with time markings to say what needs to be changed. But I'd love to be able to highlight the audio boxes with different colours (red for re-record narration, green for adjusting P-pops, yellow for audio quotes that need to be verified by an independent source etc). This is how I run my email software - different colours for different types of emails/work. This is super handy because it's easy to get lost in the all the microedits and reviews at different stages. Before hitting publish, I could zoom out and ensure there were no coloured boxes left and then know it's ready to publish.
