I was hoping for more of a 'graded' look, rather than exposure and contrast...

Yayyyy

I would love color controls as well as simple filters such as within Photos app on phone. Choose filter, adjust strength with a slider. Thank you for considering!

This is a must. It's critical to be able to adjust colour, so it currently requires encoding the video an extra time after making adjustments in FCP. Would LOVE colour wheels, since it's usually not enough to correct just temperature and tint. Usually the white balance needs to be corrected for the shadows / mids / highlights individually

Yes please - this would save me from having to import into Final Cut or Davinci Resolve. I would love to just use 1 app - I do not need fancy colour grading. Just simple filters would be great.

Yes, please. Just keep it simple, too, like adding an audio effect in Descript is now.
