Podcast iOS App - Transcription Scrubbing

This is purely a concept. An idea I had one night whilst using the Podcast iOS app - transcription scrubbing - the ability to see a transcription of a podcast whilst scrubbing.

High speed scrubbing would happen as you drag close to the timeline. The text would be small. As you drag down away from the timeline, the scrubbing would be finer and more precise with larger text.

This is purely a concept, I have no idea about how or if it would technically work!
