sublime text new line loses indent

Question

I have a problem that is causing me lots of extra keystrokes in sublime text. When I create a couple of new lines, the indentation is correct. However, if I up arrow back to those new lines, the indentation is gone and I am back at position 0 (happens for all file formats). Am I doing it wrong, is this intended behaviour? I like white space in my code so this is a pain.

Recreating: Write function code e.g.

    function Bob(){
        | indent starts here
    }

All good. I then add a couple of new lines, up arrow back to the middle and I get this:

    function Bob(){
| indent starts here
| indent starts here
        | indent starts here
    }

I would like:

    function Bob(){
        | indent starts here
        | indent starts here
        | indent starts here
    }

Any suggestions please - apart from changing my coding style :-) Thanks.

Add the following to your preferences and you should be all set:

"trim_automatic_white_space": false,

The default is true, and when set it trims white space added by auto_indent when moving the caret off the line.
