Although it is true that there are two similar ways of doing things,
this is more for if the event which one wishes to log has already
occurred. With the other feature one must activate the log first.

The other option: if one is about to debug one goes and activates this
to check for logs.

This option: if something already happened and one wishes to get it
without connecting the phone by ADB and using 'adb logcat'.

They serve overlapping but distinct needs.

Edward
