Have a look at the patch code to see if the included help notes are clear enough to be usable.
All 5 Replace: lines can be customised as required. If that's too complicated simply enabling the patch will look like the 2nd image in the 2 screenshots (default vs. patched) attached below.

If the patch is considered both useable and useful on a Libra, I can look at creating similar patches for the other Kobo model groups. Feedback welcome.

Place the patch code in nickel.yaml (or wherever you keep all your other custom nickel patches).

ETA: This beta patch is not suitable for kobopatchers who have set their Kobo locale to Chinese-HK. The space occupied by some of the Chinese-specific code was commandeered to simplify this patch for other users.

I added this to my list of patches that I use. great patch, IMO. I am using Libra 2
