I would like to give feedback to Gamma.app that you should have a function for background music during presentations. When giving a presentation, one should be able to add background noise or music playing in the background. You should be able to upload your own music or choose from already provided background sounds and music from Gamma. It should also be possible to adjust the volume and choose on which slides the music will be played and at what time in the music.

I'm a UX designer and we already have a lot of presentation apps on the market, but I think this would make Gamma the obvious app for everyone if you implemented it! Thank you very much.
