> One last thing: if I may suggest, you should replace the default picture by one with fewer characters: the german β, the spanish Ñ, and the scandinavian character (oslash, ae) may be nice to have, but they may play against you: French users may see them as irrelevant, and cluttering the keyboard. This is a very good suggestion! I should definitely show a simplified screenshot, and only introduce the extra characters in an advanced section. This should make it look less overwhelming. > For similar reasons, you may want to unify the blue and the red overlays. I've figured out that the right Alt did toggle the blue overlay, but I still don't understand how to get the red one. For other readers, you're referring to https://qwerty-fr.org/ https://qwerty-fr.org/. Blue means that it's accessible with AltGr, and red means that the key is a dead key. In a nutshell: – Lower left corner: no modifier. – Upper left corner: Shift. – Lower right corner: AltGr. – Upper right corner: AltGr + Shift. I agree that this is confusing, especially since the keyboard widget doesn't highlight the layer when you press e.g. AltGr + Shift so it's hard to know what's going to happen.
