An idea about resolving overlap link hints!

[OItisTang]

When one or more link hints overlaps,
maybe we could use "-" key(or something else) then the topmost link hint keys to hide it.

For example,

[bottom]"AA", "BB", "CC"[top]
----------------------------------------->

I want to click "AA", but "CC" hides other link hints,
so I enter "-" then "CC", now "CC" disappears,
then again, I enter "-" then "BB", now "BB" was removed,
the one what I really want, "AA", now is so clear!

This method does not effect existing link hint generating algorithms,
so it may have minor impact on existing code.

BTW, I have become a crazy fan just after I heard Vimium can turn Chrome into a vim style browser.
Now if the overlapping problem resolved, Vimium would be perfect.

I'd like to see the solution provided by VimFx (a Vimium clone for Firefox, see https://github.com/akhodakivskiy/VimFx, at the bottom): when pressing Space or Shift-Space while in the link hinting mode, z-indices of the hints change so that the hidden ones become visible. By repeatedly pressing Space one can make any of a chain of overlapping hints visible.

Specifically, this logic is implemented here:
