I know that if you do "read to end" at 100Hz you
will bring your machine down.
This is not the point here (or if it just switch automatically
to "count from end" mode when new data are comming in).
For Planck we are monitoring more than 2000 parameters
and some have a very low sample rate (1 Hz or less).
And in some cases you may want to be in "read to end" mode
even when you are live. And in this case the fact that
"play" switch automatically to "count from end" is an
expected feature. I don't see the problem here. Is it a
big thing not to switch mode when we don't ask for it ?
And by the way I think there should be only one button
that switch from "pause" to "play" when you hit it.
It is very misleading to have two buttons in the bar. I never
know which one to hit to go back to "play".
