Alias field to replace item id

Hello

I love component creator. And one feature that I would love is an alias field type, to replace the item id from the url.
I know this is hard to achieve. But it would be an awesome feature and I've seen many people making questions on how to to do this.

Normal urls look like this:
mysite.com/component/view/333
Where 333 is the item id.

Alias field should replace that itemid in the url, so that the it looks like this:
mysite.com/component/view/my-custom-alias

Wouldn't that be nice?
