How to sort icons for a sprite?

Question

css

There are many icons for one site, here is a screenshot.ru/336a19543267af0f001420c6637fb9d9 I sorted them by folders, footer, main, etc. Do I need to place everything on the sprite in turn (not only first the icons from the header, then from the menu, etc.? And also in the footer itself, for example, from left to right?) Tell me a service where you can generate a sprite and arrange the icons in the order I need. The one I know, you can't rearrange the icons there.

Answer 1

It is not necessary to sort them, calm down.
PS The folders on the left smiled))

Answer 2

Weird question. It's like you're manually stuffing them into a sprite.
