Thanks for pointing this out, will look.

I'm insisting with this just to be sure that I'm not using mutt any other way than
I should. I've configured threading, but I don't know how it shows on your end.
So:
I've sent v1 -> you said change color and function and asked about active ->
I've send v2 with color and function *changed*, and contiuned the conversation in the
 email thread about active.

Expectation was that the active stuff was to be decided and then a v2 should
have comed from me?

If yes, this is the "process" part I was previously referring to, that I don't know.
