Minibar length should be decided by an option

[Riajyuu]

Minibar Length SEEMS to be currently not auto-adjusting toward location bar length. When you remove or add toolbar buttons in UI customization, the length does not change. This is most obvious is when you hide your search box into sandwich button. So it will be better if minibar length is same as user's current length of location bar.
But sometimes this looks not brief in UI. So option can be introduced thus:
i) overriding: from X pixels to X pixels
ii) fit to current location bar length
But sometimes it is possible to achieve both option

The point of the mini bar is to be "mini", hence the name. ;)

For this case I'd rather just add an option to show the full toolbars altogether. But the amount of toolbar buttons doesn't matter as they don't appear in the mini bar. So you'd simply have a longer space to see the url, and in most cases (speaking strictly security-wise at least) you really only need to ensure you're in the right domain anyway. So, again, I don't see the gain here either to be honest.
