Split Alphabet Hints to have some controllable Weights available to the user

https://github.com/philc/vimium/discussions/4700

TL;DR: I'm using:
sadfjklewcmpgh with the goal of weighing towards the left hand

I noticed however that "e" (right-hand) seems to show up earlier than many left-hand binds including two-letter binds. I would like to have some sort of weighing; even if there's "primary link hints" then "secondary link hints" which will weigh the primary link hints to exhaust entirely including a configurable length (2 is fine for my use-case) before the secondary hints appear. I want everything from "fc" to "vp" (both left hand only) to show up before e appears for the first time.

Perhaps the more common usecase is somewhat opposite for vimium users; wanting to spread any multi-key maps out to the other hand which is otherwise idle if you don't use a mouse.

Perhaps order of keys can be taken into consideration too.

Updates from original post - I had a look at the source code and can't see much in the way of weighing; I think I see the opposite.

No file or test is named. Start by tracing Vimium's hint-generation and ordering code, then inspect how the current key sequence is weighted; done should provide configurable primary and secondary hint groups so the requested left-hand combinations appear before secondary keys.
