AnkiMobile only supports user actions 1–8, while AnkiDroid
supports user actions 1–9. Could AnkiMobile be expanded to include user actions 1–9 as well? This would ensure that both clients have the same number of customizable user actions, making it easier to standardize Anki templates.
Each action doesn’t need to be unique across templates or sides though. For the first template, you could have action 1 reveal the cloze, and for the second template, action 1 reveal option A, and so on. It’s in the user’s interests to minimize the amount you use, so they don’t require a controller with a mountain of separate buttons, or a giant top bar.
