Hi Yutaka,
No I don’t know about that :-? Thanks for the tip, it helps a lot. :-D

this has to be an option if I change this behavior.

Though I can’t find an option why you should change it …its just that other editors’ numbering feature behaves like that—-numbers inserted is always under a same column. I personally prefer that…our current method is strange (I think), after all why would a user wants to create a huge number of newlines with only sequence numbers in each line?
