Startup Idea: Custom HIT Filter for mTurk

Startup idea to develop a script or software for browser extension (specifically Firefox) that allows users to filter out unwanted HITs on mTurk so they can focus on tasks they actually want to perform.

The idea that I have actually stems from mTurk. There are a ton of HITs available that I don't want to do--these usually involve audio transcription. I don't know if it's possible to write a script or piece of software for Firefox that would allow me to hide those HITs. That could be very beneficial, and I'd be more than willing to pay for it.
