Describe the new feature you would like

It would be nice to have Vitals show the battery of bluetooth devices, like headsets, keyboards, mouses, etc Not sure if it is in the scope of the project to add this, but as it would be nice for me to have it, I'm creating an issue.

I use another extension for this purpose, but it would be nice to have it on just one.

Some visuals of the feature:

What other extension do you use? This wiki entry talks about it - ultimately battery info would need to be in /proc or /sys. Are you aware of the battery info being exposed in these directories?
