Momentarily I have that idea of a traffic light icon. If the trigger is
deactivated it would be crossed out.

That countdown thing is a good idea.

Ups, never looked at that.

I think you're right here. I'll increase the resolution < 30s instead.

There are a few things, that I will try.

Probably this pricipially is the same thing that Martin wants. I can
manage the trigger for that. But as the trigger can (and should) define
a minimum duration of the threshold the split has to happen 'in the past'.
That's a bit difficult for me. But I'm sure with some help of Linus these
difficulties can be overcome, too.

Which makes me realize that it isn't possible to change the trigger settings
while recording at all yet. Another thing to do :)

A good idea. It could be applied even while playing back!

What about modes like "Off", "Stop & Go" and "Split" then?

You and Martin are really great help that I appreciate that very much!
Yesterday I used the triggered recording for the first time while band
practice. It worked flawlessly - until the batteries were drained after
3 songs. :(
