Feature description:
set the currently playing song/media as the phone ringtone
Using custom start/end, while using built in waveforms to visualize the ringtone.
With smoother fade/looping setting.
Problem solved:
Directly setting the ringtone from within the app, this is built in into almost all android media players.
One work around is to export the media using the download feature and then using another media app to achieve this goal (for example Samsung music)
Brought benefits:
Nice to have instead of relying on other apps
A work around does exist and this might not be implemented duo to development priority or very niche use case
