Feature request: Keep same letter combination for the same button/anchor text on following links via f

As as vimium user, I always use links by pressing the f key and entering the relevant key combination.
As a web surfer, I browse sites that have consistent naming of a buttons and anchor tags.
Yet vimium applies different key combination for the same button values.

For example, github.com almost always has the button row: Watch, Unstar, and Fork.

Yet when I press f, "Fork" might get assigned SD or SF. So I can never trust a pageload to behave the same.

Or in pictures:

While this is nothing big of an issue for the github experience, I really got irked by it on the stackoverflow.com review queue, I can never be sure what combination to press to either Accept or Reject an edit. Sometimes skip is SS, then it is SD, then it is SE.

So as a feature request I kindly ask for vimium to be smart enough to keep to track the link key combination it has previously used for the same value of a button and anchor text to be able to just know the right shortcut for certain sites.h

Start by tracing the link-hint flow activated by the f key and how it assigns combinations to buttons and anchor text. Define how the site and text are identified and persisted, then verify that repeated page loads give the same combination for matching labels while still handling conflicting or changing links.
