Please keep convention of using add/remove in functions names when you
add/remove stuff from db. (this applies to all other patches as well).

I'd start from 0 and just increment when needed.

Comments. Also if that makes code more readable maybe it makes sense to define
constants for that and avoid magic numbers in first place?
