Frustrating when the jump hints are translucent as it makes hint very hard to see. Also I dont find the green hints very useful, I use vimium in the browser and find that it's best to be minimal. Usually I'm not intending to be super precise and just want to jump to an area and then adjust with h+j+k+l

Describe the solution you'd like
There should be an option to make all hints have full opacity. Id even argue that there should be an option to turn off the green hints as well, so you can have: only full opacity yellow hints

These would be optional and therefore not affect the core functionality.

Additional context
Here is a picture of what I mean, as you can see hints like JJ and R are clear but those of GG and FF are harder to see (when you view the editor at fullscreen and not zoomed in like it is here) and IMO the green hints just get in the way and don't provide any benefits (its useful to know what you've typed but id argue the cons are at least equal to or greater):
