Caching improvement suggestion

[ErrorTH]

Hey guys.
I've recently noticed the style caching feature. It caches stylesheet to separate file, reducing page size. It's nice.
But browser caches are buggy sometimes, and it's a pain, when you change something, and users can't see it immediately. Espescially when you change css and template together.
CSS is cached in style_images/css_{skinid}.css
Why not cache it into style_images/css_{skinid}-{a_couple_of_random_chars}.css and store a new adress in a template bit or something?

The same goes with avatars. Filenames are stored in database, why not add random chars to them, so the changes will be visible immediately?
thanks

Linked to this, I'd like to see a seperate style_* folder for the CSS, it's a bit random having it in the image folders to be honest. This is the first thing I re-add after upgrading my board.

this is really a smart idea, i have mebers always complaining that they added a new avatar but don't see it changed.

thanks.
