[Q] Less Frequent Sounds, i miss it.

Hello,

i've done a search around but wasn't able to find useful info, apologies if i missed anything.
Problem: i love, and need, Less Frequent Sound feature.

- Lollipop: a few custom ROMs include it, not many. Any Xposed module working on 5.1.1 to have the feature?
- Marshmallow: do you know if any similar feature will be included?

Thanks in advance
