Perhaps that's one of the reason why Stack Snippets can be hidden on browser. Even if we press "Show code snippet", the code-block will be shown with vertical scroll bar, preventing the need to scroll down all the way. This behavior also applies to general long code-block on browser (example post on SO).
Now, I am not suggesting to add scroll bar for code-block in Android app since AFAIK adding
ScrollView inside another
ScrollView is generally not a good idea. (It might confuse the app whether you want to scroll the post, or the code-block, and personally it annoys me anyway).
The problem is, I'm not sure how we can display these important elements of SO efficiently on native app.
At least, I'd want to request a feature to enable hiding/showing Stack Snippets on Android app. Bonus point if it can also be applied to long code-block (minimum of 30 lines?).
Or else, do you have any other suggestions?
