Discord DM Management, DM Voice Call Suggestion

I would like to share a suggestion for future updates as I think it would make the app much better as a whole.

Firstly, having an all clear button of some-sort for direct messages to be deleted permanently on both sides of the party. This feature would be great for people who desire to delete a DM conversation in its entirety and it would avoid problems for those who simply just want to close the DM.

Secondly, I thought of this idea for direct messages' voice calls on mobile phones. What if you could voice call in the form of a phone call? So without the call to be brought forward through the mobile's speakers, but have an option for people with mobile phones to have the sound coming through the speakers or from the phone's calling outputs? It would be easier and it would avoid needing to use earphones as you can simply hold the phone to your ear.
