Like add property in components/bootstrap.php
Where you can specify url of bootstrap scripts/css etc?!
We should have all thirdparty assets as external dependencies anyway, by the way. I personally don't think we'll be able to make such a change in any near future.
For now our best bet is to compress all such an assets as hard as we can.
As for your original proposal, sure, I want to do something like this for very long time, but I'm equally sure that we need to have quite a different architecture for it first. Maybe you can hack something quickly, though, but I'll not do it.
Yeah, exactly like a packages system. Thank you.
