I'll try to answer from memory:

Yes it's the thread id. To check. just launch a thread manually using a
function that just do a log.

Not sure about this one, I don't use scoped logging at the moment. If you
tried an example from the doc but it didn't do what you expected, then
report a bug.

I would not use trivial logging as soon as I want to customize the logging.
The reason is that trivial logging is a full setup which is easy to
reproduce and easier to modify if you set it up manually.
So I encourage you to decide how you want to log (for now) and setup
formatting and sinks manually. It's really not hard,
just a bit alien at first to write.
