Handling many choices in List/Checkbox

[AuHau]

If there is high number of choices in List or Checkboxes the behavior is far from optional. The list will overflow the screen and navigation becomes practically impossible.

I suggest limiting the size of "scrollbox" to a certain number of lines and scroll through the box when person navigate to the end/beginning.

Also, I would suggest adding filtering/auto-suggesting feature, which would allow the user to start typing while in the List/Checkbox question, which would filter out the choices displayed.

@magmax do you think the proposed solution&feature is feasible? If so, I could work on it, if you would accept the PR...

I have written a fix for this at 204f566, but it has some visual problems.

The inicial solution was too easy, but I'm not sure about how to solve the problems and how to combine it with carousel.

Any ideas?

No matter how long the list, shouldn't carousel only loop back around to beginning or end when the "real" first and last options are surpassed? (And not influenced by the "first" and "last" options within the currently displayed "sub-window" of choices)

It's not implemented for checkbox.

Should be solved with #72
The current solution only shows limited number of choices, but not additional features.
