With an indentation of 1 space only (as in the screenshot), the indentation level is not so easy to see. That's why the indentation should not be too small. Having a large indentation and functions that are not too long will make it easy to see the indentation level without any extra help. That's why the Linux coding standard, for example, requires an indentation of 1 tab = 8 spaces.
