Thanks for your positive feedback.

Either use an external editor, if you do not like the internal one.

Or set CRLF in your session settings:

Editor changes Linebreaks #0D0A into #0A
Is there a possibility to change this impossible "Feature"?.
Did again waste a lot of time

I used for some "quick corrections" in some scripts the Onboard "Editor" (Bearbeiten), but crashed it, because all edited scripts Split did not work anymore.
Took a time to find out why.
Because your "intelligent" Editor changed all Linebreaks from #0D0A to #0A ...
Means that PHP scripts with explode expecting #0D0A as Delimiter fail.
