Feature Request: Improvement of Queue management

[maste9]

As much as I like the simplicity of Otter I find it difficult to manage the current playlist (queue). So I like to propose some humble wishes for further development:

• a button to just clear the queue (already in tip-version)
• mark several tracks and delete them from queue (e.g. by swiping to the left or after holding one track to enter mark mode)
• delete a track by swiping to the right (an example for a queue management I like you'll find at https://github.com/AntennaPod/AntennaPod)
• nice-to-have but maybe too complex: saving a queue as a playlist for the logged in funkwhale account. (already in tip-version)

Besides my wishes: Thanks for your work. Otter is definitely the best app to work with funkwhale for Android at the moment.
