This is something I brought up about a year ago because I have the same problem. I've mostly just done trial and error. If a spoke goes away, I hit it again, but obviously that's a stopgap. Anything come of that, mk?
Sadly Meriadoc, you have met and broke bread with the Hubski team which all but ensures that this feature could never be implemented on your behalf. We all know full well that the cobbler's children go unshod. For the record, I obviously support accessibility features that address issues like this :)This is something I brought up about a year ago because I have the same problem.
I'm just so blind and all I want are soles on my shoes and maybe a nice pie and some money :c Also, slightly related, but does anyone know if regular blindness affects color-blinded as well? I'm very much of both, but I get the feeling that my bad vision makes my color differentiation that much worse.
Nothing did, but I'll add a toggle that uses reddirecpthoo's sprite.
